17 years old and definitely not wanting to be pregnant. (yet) My boyfriend and I had sex for the first time ever in the 19th. My period was due on the 23rd.... Around the 21st, I noticed a very small amount of brown discharge. On the 22nd, I notice very light bleeding. It was a brownish-red. I seemed to be implantation bleeding. (my period doesn't normally start off light before becoming heavy). The morning of the 23rd, I woke up with what seemed to be my period. (lots of bleeding, i bled through my pjs). I don't normally have cramps and nasea during my period, but i am having those symptoms now. As the day progressed, the bleeding got heavier, and had A LOT of clots in it. (my period doesn't normally clot) I passed one clot that was about the size of a quarter or bigger. I looked it up, and everything is pointing to a miscarriage. could this be true? could i still be pregnant?
