Have you tracked your ovulation? Seeing that an egg normally only lasts about 12-24 hours, it's a miracle that so many women get pregnant at all. I have always been told that you shouldn't worry about fertility until you have been trying for over a year. I've always had weird cycles, but since having babies, I am like clockwork now. I always like to suggest clomid or chaste berry extract. The clomid is prescription, but chaste berry extract is an otc pill you can get from gnc, vitamin world, or any health food store, and it helps boost ovulation, and also relieves menstrual cramps. What does your doctor think? Well, keep us posted, and don't worry too much. It normally happens when you least expect it!!!
