Ovulation?11/20/2009 |
I am 33 years old. I was pregnant last November but miscarried January 9 2009 and was diagnosed with a partial molar pregnancy. Devastating. We got the OK to try again in August and have been trying. My cycles have always been regular. I was on birth control for 10 years and then last year went off birth control to conceive. After my miscarriage my cycles were messed up for a couple months and then I had 4 cycles at 30 days and have had 2 cycles at 28 days. I started using OPT`s and charting, but I have not yet gotten pregnant. This cycle, my BBT is erratic and hard to predict and I have yet to get get a positive on the OTP. I`m confused. Am I not ovulating even though I have no other problems? I thought anovulation meant I`d have erratic periods? I`m incredibly concerned given what we`ve been through with the loss of one child and with getting older. Please help me figure this out.
I believe you are asking about the use of ovulation prediction kits.
Most women who have regular periods in a pattern between 24 and 35 days apart are ovulating regularly. Ovulation usually occurs 14 days before the first day of the next period.
When there is doubt about whether ovulation is occurring, it can be checked in several ways. Basal body temperature (BBT) can be checked each morning, and the body temperature will rise about one degree Fahrenheit a day or two after ovulation occurs. Urine tests can be purchased over the counter that measure a hormone called LH in the urine, which appears one to two days before ovulation (but then disappears, so if you do not check for it in the two to three days around ovulation, you will miss it.) Or there are tests a physician can do, such as a series of ultrasounds to demonstrate ovulation, a blood test for progesterone in the second phase of the menstrual cycle, or a biopsy of the uterine cavity at the end of the cycle.
Most women trying to get pregnant do not need any of these tests, and if you have only been trying to conceive for two months and conceived previously, there is no reason to think you cannot get pregnant again.
