So about 3-4 weeks ago I had unprotected sex and about 2 weeks ago I started getting pregnancy symptoms, a few days ago I woke up and when I went to the bathroom there was a light amount of blood. It was only there when I wiped so I thought it was implantation bleeding. Then as the days continued it got heavier. The bleeding stopped last night.. I bought 2 pregnancy tests just in case. Should I still take them?
