Ovulation problem: It is most likely that you are not ovulating. Your ovaries will still make estrogen, so your uterine ling will grow and thicken. But with no ovulation your periods will be very irregular and, of course, you won't get pregnant. Get advice from a fertility doctor. There is a drug, clomiphene, which may help you ovulate and become pregnant - if this is your desire.
