My wife experienced double menstruation ie 3rd April-7th and another one on 9th.The second one was so painful. She feels alot of pain during/after sex and lower abdominal pain. She conceived after we were given herbs by aherbalist but the baby died in her. She delivered adead baby but we attended antenantal services in agovernment health centre III. She can't become pregnant when we have unprotected sex even during fertile days. What is the cause and what can we do to stay happy in our marriage?
