Impossible: That is impossible to answer. You are missing the last menstrual period, the length of your cycles and your due date. Get these important pieces of information and then we can help!

A guide: The egg lasts about 1 day and sperm can survive 3to5 days. The key thing is to know when you ovulated. A woman who is very regular and has cycles of 30 days usually ovulates on day 15, for example. This is just a guide and menstrual cycles can vary from month to month. Your obgyn doctor is best to advise you.
