I'm 17 years old. My boyfriend fingered five days ago and he accidentally scratched my vaginal walls. I had very little bleeding and then it stopped. The day after, I had mild cramps but eventually it stopped. And then this morning, when I woke up, I found a tissue-like discharge on my underwear and I had no idea what it is. I'm supposed to be having my period now. I'm having severe cramps too. Someone help me?
