Pregnancy test : Will help sort out whether this is the reason for your late period. There are a variety of other causes including polycystic ovaries among others. Your doctor will be able to assess and if necessary arrange tests to help diagnose the exact problem

Pregnancy test: A woman, who has missed her period and has had intercourse, even though, being very careful, should perform a pregnancy test.
