me and my girlfriend have sex. and she is delay for 2 months. but we try to pregnancy test and its negative. is she pregnant?
Pregnancy tests are really only accurate when they indicate a pregnancy. By default they read "negative". They don't work with all women either.
Test again. Make sure she uses a NAME brand. She MUST use her first morning urine - her wake up pee - to test. Follow all directions carefully.
She should follow up with her doctor to find out WHY she isn't having her period.
