Is it possible for BBT to go up and stay up for several days then get back to normal without having ovulation? Or a rise in BBT always mean ovulation?

Old Wives Tales: BBT is not in any way a modern or exact way to monitor anything about your menstrual cycle. If you are having monthly periods you are ovulating. Your ovulation is like clock work, it does not vary. Many women learn to feel when their ovary releases the egg. Ovulation happens just shy of half way through your cycle. The five days prior to that event is when sperm will cause pregnancy. Read more

Ovulation kit: If you are using an ovulation kit then there is no reason to be checking BBT. BBT is very unreliable. It was used to detect ovulation historically when better options were not technologically possible. If you want to track ovulation your ovulation kit is more reliable. Read more

Either one: Based on this information you could have ovulated on either day. It is not usually clinically important to narrow it down to the exact moment of ovulation. Just have sex around that time. A one day discrepancy is not going to make much difference. Read more

Spotting day 10/11, + OPK day 17/18, spotting day 19/20/21, BBT temp still not risen. Ovulated yet? What's happening? Not experienced annovulation

Spotting day 10/11, + OPK day 17/18, spotting day 19/20/21, BBT temp still not risen. Ovulated yet? What's happening? Not experienced annovulation

Maybe: Best test for ovulation is a blood Progesterone level of > 3 ng/ml. Other than pregnancy (which is proof positive) the other tests are less specific. I think that bbts are kinda cruel so rarely suggest that my patients do them. Opks have been shown to only increase patient anxiety and not improve chance of pregnancy. So for patients with regular cycles I suggest sex on cyclec days 10/12/14/16. Read more

How soon after ovulation does BBT rise? My BBT raised today from 97.3 to 98.2.When did I ovulate?

Possibly 1 to 2 days: Progesterone is produced after ovulation. The Progesterone changes the setpoint in the brain to raise the temperature. This occurs approximately 1 to 2 days after ovulation. Read more

I started taking bbt. One month I am seeing a rise in BBT but other month no rise. Does that mean I am not ovulating? Period is very regular.

Periods?: Do you get a regular period? If so, 99% you are ovulating. Bbt is notoriously difficult for some women to use, and opk is not always accurate. Read more

Possible to ovulate without a BBT temp rise? It has been 24 days since my d&c and no sign of ovulation. Possible I will not ov before next period?

Possible: There are a number of things that effect ovulation, and a number of things that may effect the temperature response. If the d and c was for a miscarriage it may take longer to ovulate after because of hormonal changes. Read more

I measure bbt. I had 3 risen temperatures for 3 days after ovulation (14th day) & then low temp for 5 days until today. Is it normal? What to expect?

Normal: What you described is normal variation during a menstrual cycle and you should expect a normal next cycle unless you engaged in sex at the fertile period, in which case you could be pregnant. If you miss your period, do a home test 4-5 days after missed period, use first morning urine and follow the instructions in the kit, carefully. Read more

What causes an elevated rise in LH levels after ovulation? And what are the problems this can cause? I'm 28yo

LH surge causes ovul: Actually it is a surge in the LH levels that cause ovulation. This surge is due to other hormones being present in your system. There are number of problems that might cause an interference with an LH surge like Poly cystic Ovarian disease, Ovarian Failure, high prolactin levels. If you are having ovulation problems or symptoms of no periods then please speak to your doctor for a checkup. Read more

Why haven't I got a BBT rise this month after ovulation? I'm now on day 30 of my cycle of a usual 35 day cycle

Why haven't I got a BBT rise this month after ovulation? I'm now on day 30 of my cycle of a usual 35 day cycle

BBT is not as useful: As some have been lead to believe. The much more sensitive way to determine ovulation timing is with the use of over the counter LH surge or "ovulation prediction tests". The BBT can be affected by stress, time of year, the instrument used to take the measurement, and of course illness or even vaccines. Travel can affect BBT. Also, you may have not ovulated this cycle. Try an OPK, for best info. Read more
