So according to my app I am late by two days. Normally when right before I start I get some cramps , tender boobs, irritable and all the other things. Yes I am sexually active and I don't use any kind of preventative other than the "pull out" method. I took a pregnancy test yesterday and it came up negative. I am having some symptoms and normally I get a brownish discharge before hand, but I haven't had that at all. What should I do?
