Basal Body Temperature Questions

Q: What will my BBTchart tell me?

A: The goal is to find out if you are ovulating and help you time intercourse. If you see a definite biphasic chart, that?s a good sign. You can also tell whether your luteal phase is long enough if your temperatures are up for at least 12 days after ovulation.

Q: How long should my temperature stay up after ovulation?

Ideally, 14 days. Some doctors say anything over 10 days is acceptable, but it really makes sense to test for luteal phase defect if one typically shows 12 days or less of high temperatures. You can test for luteal phase defect with a serum progesterone level and/or an endometrial biopsy. Many doctors will want to see two cycles of low progesterone or out of phase biopsies before making a definite luteal phase defect diagnosis.

Q: My temperature dropped for a day in the luteal phase, does that mean this cycle is a bust?

A: Not unless it stays down. Some people have a short drop that may go well below the coverline that is a secondary estrogen surge (which may be accompanied by mucus).

Q: How long should I chart before seeing a doctor if I suspect infertility?

A: Good question! If your cycles are irregular, you shouldn?t waste time on BBTs alone -- see a doctor and find out what may be causing the irregularity. If you do have normal-length cycles and decide to start charting, you only need to wait about 3 months to establish a problem and seek help. For example, if you have a 28-day cycle, but ovulate on day 18, and that happens 2-3 months in a row, you should see your doctor. Otherwise it depends on your age and urgency. It?s not a bad idea for everyone to get preconception advice and bloodwork -- test for immunities to rubella, chicken box, fifth disease, also test for anemia and thyroid function at a minimum.

Q: What are average BBTs?

A: The average range of BBTs is between 97.0-97.7 Fahrenheit (36.11-36.5 Celsius) before ovulation and 97.7-99.0 Fahrenheit (36.5-37.22 Celsius) after ovulation. Ideally, a woman?s temperature will not bounce around more than .5 degrees in the follicular phase and will stay above the coverline during the luteal phase.

Q: My BBTs are lower/higher than average, what does this mean?

A: Either case warrants checking your thyroid. Low BBTs are often a sign of hypothyroid which can cause some fertility and pregnancy problems. Excessively high temperatures may indicate hyperthyroid.

Q: I did and ovulation predictor kit, how long after the positive should my BBT rise?

A: You should ovulate 12-48 hours after the positive ovulation predictor test, and your BBTs should go up within 48 hours of ovulating. It can take up to 4-5 days to see the rise, but ideally you see it within 3.

Q: My chart looks more like the Rocky Mountains than anything else, what does that mean?

A: Most likely a) you are not taking your BBTs consistently or sleep erratically, b) you are taking your BBTs orally and you sleep with your mouth open, or c) you are not ovulating. If being more consistent, or switching to taking your BBTs vaginally or rectally, doesn?t help, you should go to the doctor to have your hormone levels checked out and see what may be causing your anovulation.

Q: How late in a cycle can one ovulate?

A: It is possible to ovulate very late in a cycle -- there is not any day limit -- so a long cycle doesn?t mean there is no hope. Long cycles do, however, reduce opportunities to get pregnant and warrant looking into. It is also a good idea to have at least one cycle every 3 months, brought on by medication if needed, so that the uterine lining does not become too thick.

Q: Can I tell I am pregnant from a BBT chart?

A: You are most likely pregnant if your BBTs stay up for 18 or more days after ovulation. It is also common to see a triphasic chart, a second shift sometime during the luteal phase, when pregnancy is achieved.

Q: Do I really need BBT thermometer, or will a fever thermometer do?

A: A BBT thermometer is more reliable and more accurate. In glass thermometers, fever ones are only accurate to .2 degrees Fahrenheit. You really need it to be accurate to .01 degrees. The main plus of the digital BBT over a fever BBT thermometer is speed. The BBT digital is more accurate for some people, and it only takes 30-60 seconds, which can matter if you are waiting to go to the bathroom first thing in the morning. The digital ones are harder to break and remember the temperature for you if you don?t want to chart it immediately.

Q: Are my BBTs as accurate if I am taking fertility medications such as Clomid or injectibles?

A: In a word, no . . . but that doesn?t mean they don?t tell you something. Clomid often causes elevated BBTs around the time of taking the medication, and it appears to be more common to have a triphasic BBT on medications without pregnancy. It is also more common to have a long luteal phase without pregnancy. Other monitoring is more reliable when on medication.

Q: Will taking progesterone raise my BBTs?

A: It may raise your BBTs, but natural progesterone usually only causes a minor elevation (.1 or .2). Progestins like Provera can raise BBTs as well.

Q: My BBTs were up for more than 18 days and I am not pregnant. Why?

A: That?s a question for your doctor. If you were on medication for fertility problems, that could cause an extended luteal phase. It is also possible for a corpus luteum cyst to lead to a longer luteal phase. The best thing to do is see your doctor for a blood pregnancy test, exam and ultrasound.

Mucus Questions

Q: How can I tell fertile mucus from semen?

A: Fertile, egg-white mucus should stretch repeatedly in only one of two strands. Semen tends to be a little cloudier, and often stretches in several spiderweb-like strands. You may be able to stretch it a few times, but then it will begin to break.

Q: What is this about taking Robitussin to help with cervical mucus?

A: Plain Robitussin, or any generic with the guaifenesin as the only active ingredient, is an expectorant and helps thin mucus in your body, including cervical mucus. It does not create mucus for you, but can thin out thick mucus (a common side-effect of Clomid). The recommended dose is 2 teaspoons 3 times a day with a full glass of water, but you can take up to the maximum dose on the label. It should be started about 5 days before ovulation and continued through ovulation day. The water is very important since your body needs the fluid to create the mucus, and the guaifenesin can cause constipation.

Q: I?ve heard I can use raw egg whites if I don?t have enough fertile mucus, is this true?

A: It is suggested in the book Taking Charge of Your Fertility by Toni Weschler, but it probably is not a good idea ? most eggs in the United States contain salmonella and you risk the possibility of becoming infected. It would be better to use something else as a lubricant. The rest of the book is great, but this is one piece of advice that may be safer to avoid.

Q: What are some sperm-friendly lubricants?

A: Most lubricants will kill off some sperm so it is best to use as little as possible. It is reasonable to use a small amount of over-the-counter brands such as Astroglide, or ask your doctor to order you some FemGlide. Saliva is not a sperm-friendly medium, nor is water. Anything petroleum-based, such as Vaseline, should be avoided.
