I am 23, and I have one child. I was two weeks late for my period, and was having a lot of pregnancy symptoms. I then thought I was starting my period, because there was just a few blood spots on my panties. Then after having sex with my husband, which was very very painful, I have started bleeding very heavily. So heavy, that my tampons start leaking through after about 40 minutes. Even when I got in the shower I was bleeding very steadily. I also just started having some pain in my lower back, nothing horrible, but its there. Can anyone help me figure out whats going on?
