I have been having very regular unprotected/contraceptive-free sex with my husband for 3 years. Neither of us have any STDs, not drug users, and are active and healthy. I'm 24 years old, and he is 27. I have never become pregnant. I always have strong PMS symptoms, and a regular heavy periods every month however I never notice the "egg-white" discharge so often described when a woman is ovulating. Can I still be getting a period if I am not ovulating? Am I infertile? My husband already has one child from a previous marriage, so I think I may be the problem. Please help!
