Hello. I understand your concern. A pregnancy requires a physical and hormonal balance in the body. Infertility needs a workup of both partners (sperm analysis for your husband),along with a detailed medical history and menstrual history. I would suggest you visit an infertility specialist and undergo the tests for checking hormonal imbalances (blood tests), ovarian follicular monitoring(ultrasound) and HSG(for tubes), and others as will be asked for. We need to find out where the problem is- ovulation or tubal factor etc. Treatment will be cause-specific. It is important that you maintain a healthy diet and exercise regime as well. Do not worry. Write in if you have any doubts.
