I'm a little worried that I might be pregnant. Just the day or two ago I noticed that my breasts were somewhat tender and sore and every now and then I had a headache. Yesterday, I started to feel cramps and later that day, I realized that I was bleeding, and so far it has been kind of heavy (not light like implantation bleeding normally is). As of now, I'm not sure if it is my period or implantation bleeding, though. Now, I'm still bleeding and I still have cramps. It has been about 12 or so days after the possible conception and I'm not quite sure if I really am pregnant or not. I would like some feedback on what people think. Thanks.
