Please help I have no one to talk to about this: I still have NOT had my period since the second week of December, I took a test Monday it was negative. Yesterday I got nauseated and threw up out of no where and I cirrently have a faint headache. I want to do another at home test but not sure when to do it. I dont want to tell my fianc? until I know because we have already dealt with a false positive.
