I am normally pretty regular with my periods. This month, however, my period was late by 7 days and all the tests were negative. Last night, I used a q-tip (yes, i'm paranoid) to see if there was any trace of blood inside of me and sure enough, there was a bit of blood. So, I thought that settles it, I'm not pregnant. But the blood is still not coming out and now I'm worried again! What's going on with my body?!
