I am planning for my wife?s pregnancy. She has irregular menstrual cycle. Period occur between 28-38 days. We have aborted 1 year ago because of family planning. We are fit and don?t have any bad habits. We are trying to conceive from last month. Last period was on 17th june. We are doing unprotected intercourse from 25th june. Yesterday on 13th july the pregnancy test came negative. Please help us in this issue. Please suggest treatment and timings for having intercourses. Erection is normal ie. 15 minutes. Sometimes in rare cases when done frequently/daily, ejaculation does?t happen but erection stays.
