A few months ago my friend got physical with her boyfriend. Now, it's been more than two months since she last got her periods. She did many pregnancy tests and all of the results were negative. She gets certain period like secretions but she doesn't get her periods. She has had abdominal pain and yet again no periods. She has also taken an i-pill every time after unprotected sex. Is she
pregnant? What else can she do to be sure?
