I am 20 yrs. old and just stop taking birth control about three months ago and me and my husband had unprotected sex. My last normal period was on May 12, 2005 now it is July 1, 2005 and no period i did have spotting on the day my period was supposed to start, it was just enough to where i would only see it when i wiped, and my breast seem like they have grown overnight they are very big and i am having pains in my lower abdomen. I have took 3 tests and they have all come up neg. What should i do? How long should i wait to take another? :unsure:
