Is my girlfriend pregnant?...Pleas Help!!!!!?

It is unlikely she would be having signs such as morning sickness this early,as it takes a couple of weeks after implantation at least in the normal course of things.MAybe she just has an upset stomach.Having said that,her method of washing herself out is ineffective and not at all considered a method of contraception(I am a pharmacist and know what I'm talking about).You should use another method of contraception (as you are unmarried,I would say abstinence!).She should take another pregnancy test in a couple of weeks to make sure.
