Hi, I'm an 18 year old girl who just started her period two days ago. I have had sexual activity with my partner, though we used protection. I have had a ongoing natural weekly cycle of having my period every month but today, something odd happened. It's the third day of my period and I recently had cramps and pains. Thought it was normal until when I went to go shower, I noticed this piece of flesh, looking like jelly tissue, covered in blood. I got scared and didn't know what to think. What could it be? Please help. After showering, I felt my energy draining away from my body, getting weaker. What could this be?
