My wife and I used condoms during sex but we are suspecting that the sperm may have leaked out during ejaculation and we are not sure about it. Today i.e. 03rd may is the date of her period but she did not get it as of now. She already had 2 caesarean. Second is the girl child of 7 months old. We are very frightened about thinking of the pregnancy. Her last period was on 5th april. What should we do. Pls help.
