No, but dont listen to me i just took a family class or what ever it was called but mabye you should see the docter, but i look that up and i did some searching like in my note.(btw i take AMAZING notes..js) and looked on the internet but the doc has more info and a better way of telling
nope. could be bruising. could be ink. or a stain. or anything. if your worried that your pregnant you can get some test kits at a chemist that can tell you, but since your profile pic is a guy, i'm seriously doubting it's pregnancy.
