I am late this month but I have taken to tests and they are both negative. Sunday my breasts started to feel sore and I had problems sleeping that night because I am a belly sleeper. They are swollen and my nipples are poking out. There is some discoloration on the nipple itself. There is still pink at the top of the nipple but brown around the edge. I usually do not have sore breats when i start my cycle. I am currently 7 days late. I have had problems with dizziness and felt like I was going to vomit. Can someone please help? I have a nurse friend and she says that I am pregnant but it bothers me that it is not showing up on the test yet.
