Trying to conceive: How to take your basal body temperature

By Monica Beyer

If you've been trying to get pregnant for a few months with no success (or are even just starting out) you may want to look into charting your basal body temperature for important fertility information.

What is basal body temperature?

Your basal body temperature is simply the temperature of your body at rest. More specifically, it is the temperature of your body after a good night's sleep and before you get out of bed, move, roll over or have sex. In keeping track of your temperature and entering it on a chart you will begin to notice certain important clues to your fertility. The most valuable clue -- and the one that you will probably be the most interested in -- is your ovulation date. Knowing when you ovulate will enable you to know when to take a pregnancy test and after a few cycles you will be able to see the big picture of your reproductive health.

Why is it important?

In the physiologic foundation of basal body temperature (or BBT) lies a simple truth about hormones. There are several hormones at play during your reproductive years and they coordinate quite well in order to first ripen and release an egg, and then to nurture your womb's lining in preparation for a fertilized egg. The hormone that helps you determine whether ovulation has taken place or not is called progesterone. This hormone is responsible for raising your BBT just enough to allow for your uterine lining to become even more warm and inviting for that fertilized egg -- an incubator of sorts. And by charting your BBT you can usually determine when this has happened!

Getting started temping

You will need to look for and purchase a thermometer that is made specifically for taking your BBT. The reason that you probably don't want to use your regular fever thermometer is because it may not be quite as accurate as a BBT thermometer. One that is backlit and also which beeps when done is even better, such as this one from BD.

Quick charting tips

You should make an effort to remember the following guidelines when temping in order to remain consistent and to keep your charts as accurate as possible:

* Temp at the same time every day. Many women will set their alarm clocks, take their temperature, and go back to sleep (even easier if you have a thermometer that has a memory function). Even a half hour earlier or later may cause your results to be inaccurate and may render your chart unclear. We don't want that!

* Temp before you do anything -- especially before you get out of bed and use the bathroom. Just grab your thermometer and temp!

* If temping orally, don't eat anything or take a drink before you temp.

* Make sure, if possible, that you have had at least 3 or 4 hours of consecutive sleep before taking your temperature.

* If you don't have a thermometer with a memory function, keep a small notebook and a pen on your bedside table for recording your findings.

* You can take your temperatures orally, but if you find that you are a mouth breather or your temps vary based on the room temperature you might explore temping vaginally. Just be sure to maintain the location throughout the entire cycle -- changing from one to the other will keep your chart from being accurate.

Charting your temps

You can make your own charts with pen and paper -- or even on a computer, with a program like Excel. You can also find some pre-made (blank charts) in a very popular fertility book. Please check out Taking Charge of Your Fertility by Toni Weschler. Not only does it provide in-depth information on fertility, charting and making it all come together, it is full of hope and inspiration. You can also find software programs that will help calculate your ovulation date for you. Good luck!

Babymaking 101: 10 ways to increase your chances of conception

Alisa Ikeda

Most couples spend so many months and years trying not to get pregnant that they assume getting pregnant is what happens the moment they relax. It can be disheartening to realize there's more to babymaking than discontinuing contraception. Here are 10 simple things you can do to stack the pregnancy odds in your favor.

Most couples spend so many months and years trying not to get pregnant that they assume getting pregnant is what happens the moment they relax. It can be disheartening to realize there's more to babymaking than discontinuing contraception. Here are 10 simple things you can do to stack the pregnancy odds in your favor.

1. Eat, drink and make baby
Zinc shortages in men have been linked to lower testosterone levels and sperm counts, so men should consume foods rich in zinc, such as lean meats, eggs, seafood and whole grains. Calcium and vitamin D may improve men's fertility, so drink your milk, Men. And sip that tea, Ladies. According to a 1998 study by Bette Caan at the Kaiser Permanente Medical Care Program of Northern California, women who drank more than half a cup of tea per day were seven times as likely to conceive during the three months that the study lasted.

2. Live clean and well
Abstain from alcohol, cigarettes (even second-hand smoke) and medications (prescription, over-the-counter and herbal), and steer clear of toxic chemicals, including household cleaners. Limit your consumption of chocolate and caffeinated sodas, teas and coffees. Excessive exercise and a very low body fat percentage can lead to fertility problems in women, so stay active, but don't overdo it.

3. Stay cool and hang loose
Sperm production is inhibited by overheated testicles, so men are advised to wear breathable boxers and loose-fitting pants, avoid soaking in hot baths or hot tubs and sitting in saunas, and even cut back on bicycling and rough sports.

4. Identify your window of opportunity
You've undoubtedly heard about various remedies to enhance fertility. While it's tempting to swallow those claims, you shouldn't take anything without first consulting your healthcare provider. Frankly, nothing makes a baby more effectively than simply timing intercourse with ovulation.

According to John R Sussman, MD, an ob/gyn in New Milford, Connecticut, and co-author of The Unofficial Guide to Having a Baby, babymaking is mainly a numbers game:

* You ovulate about 14 days before you get your period. "If your cycle length varies from 24 days to 30 days," says Dr Sussman, "then you can count on ovulating somewhere between Day 10 and Day 16."
* An egg only lives for 12 to 24 hours; intercourse after ovulation is usually too late.
* Sperm can live up to 72 hours; intercourse as much as three days before ovulation could still result in pregnancy.


Dr Sussman sums it up: "Your window of opportunity opens about three days before the earliest possible ovulation and closes about a day after the latest possible ovulation."

5. Use an ovulation predictor kit
Ovulation Predictor Kits [OPKs] are a great way to maximize your chances of conception, says Dr Sussman. These will help to quickly and accurately detects the increase in luteinizing hormone in your urine (LH Surge), which normally occurs 24 to 36 hours before ovulation. You are most likely to become pregnant if you have intercourse within 36 hours after you detect your LH surge.

Charting and tracking your basal body temperature (BBT) charting is another option recommended by some doctors.

6. See your caregiver
Schedule an appointment for a preconception checkup. Your caregiver will review your family history, make sure you're in good health, and will discuss your current contraceptive method. Many fertility experts recommend that a woman stop taking the birth control pill at least three months before she tries to become pregnant. This way, your cycles can return to normal, allowing you your best chance at achieving pregnancy and helping to more precisely determine gestational age if you do conceive.

If you have not already, you should talk to your caregiver about prenatal vitamins, and if she or he recommends them for you, begin taking them even before you try to conceive.

7. Time the baby dance
Dr Sussman generally recommends intercourse every one to two days within your window of opportunity. "Some people ask whether the sperm count suffers with intercourse every day. While that may be the case for certain men, it's not for all," he says.

A man's testosterone levels and sperm count are highest in the morning, so sex may be most productive then.

8. Choreograph the dancing
Not only does it matter when you have sex; it also matters how. According to some fertility experts, the missionary position (man on top) allows for deepest penetration and can deposit the sperm closest to the cervix.

Similarly, if the woman has an orgasm, her contractions may further carry the sperm into the cervix. Avoid artificial lubricants or oils; petroleum jelly, glycerin and even saliva, which can all kill sperm.

9. Stop babymaking and start lovemaking
When you're "trying," it's easy to let the mechanics of babymaking overshadow the romance of lovemaking. Unfortunately, stress can interrupt normal ovulation cycles in women, kill your sex drive, and can even cause men's testosterone levels and sperm count to drop.

If you want your baby's conception to be a loving and unforgettable experience, be sure you relax enough to enjoy it!

10. Seek help
Though it certainly can, conception doesn't typically happen overnight. So how long should you "try" before seeking intervention?

Many experts suggest waiting about a year after first trying to conceive, depending on your history, age and temperament. Says Dr Sussman, "Couples who have not conceived after three to six months of excellent timing should be offered at least a preliminary evaluation. Then there are couples who clearly haven't mastered timing or aren't in any hurry. They can comfortably wait for a year or more."

Sometimes the mere threat of intervention is enough to make sperm meet egg.

"I knew I would get pregnant as soon as I had that reproductive endocrinologist referral in hand," recalls Kelly Moronko, mother of one with one on the way in Riverside, California. "One week before my appointment I tested positive. I'd bet money that if I check my records the referral was approved the same day I ovulated!".
