I'm not sure if I had a miscarriage or not....I've never been pregnant before....I had unprotected sex....But as far as I know he did not cum....And shortly after I had sex I had my period....Which was on time....But after that period....A week and half later my breasts well mainly my nipples were sore....If I just brushed up against them they would get hard and start to sting (I guess that's the best way to describe it)....It's been about a month since I've had sex and now my period is back on....It's on time, but its heavier than usual...I was changing my tampons at least every two hours or so....so i went out and bought some pads, cause it is such a heavy flow....When I went to the bathroom....I had wiped myself and I had a piece of skin(i guess) on the tissue...It felt kind of rubberish(best way to describe it)....And at first I just thought that it was a bloot clot....But when i pinched it no blood came out....there was a kind of roundish dark colored cirlde at one end and kind of pinkish grey at the other....I was reading on the internet trying to determine if it was as miscarriage or not....But i'm still not sure...So if someone can please help me....
