I had unprotected sex with my gf on 18 Feb. Her periods were on 22feb. She had bleeding during the sex. But she is still worrying because the periods didn't come on 22nd and now its 2 march. The main point is that ejaculation was outside. I am sure nothing went inside. She had pregnancy test on 1 and the result were -ve. Today she had home test and again it was -ve. Please help me. I am in deep deep tension what to do.
