I usually have my period on the 9th of every month and my last one was feb 9th. being that feb was a short month I figured it would come a little late this month. well here it is lmost march 20th and no period! the last time I had sex was like feb 20-21st somewhere around there. I have had cramps and spotted twice in my underwear in the last two days, it wasn't even really blood but like a little pinkish color when I wiped. I am freaking out and yes I have been stressed the last week or so. I have taken 7 prego tests all diffreent types, and all diffrent times of each day this week and all negative. Im not trying to get pregnant, but has anyone else experienced this and wasn't pregnant or would have have suggestions?? Im freaking out!! Ive also in the past few weeks have had a pap smear done, a complete blood count and donated blood...wouldn't they know by any of them??
