So I am 24, not been on birth control since 2008. I missed my period 3 weeks ago, I am always regular, even when I was on BC and off. I have taken 7 tests, all different, all negative. My intuition tells me I am pregnant, but the tests don't lie? right? Anyways, I have had some slight cramping and a dull pain in my lower region, and I just honestly want to know what's going on..Also, side not (2 of the pregnancy tests I took went to positive later when I looked at them, what could that be about? I am confused..
