Miscarriages

So recently I found out I was pregnant, scary as shit for me because I’m young. In school I had really bad sharp cramps and I went to planned parent hood they said I might have a miscarriage. 2 days later in school I’m in HORRIBLE pain and a big clot comes out bright red and everything really big. I had bleeding after wards and I recently stopped. But for some reason I’m “bloated” and i keep thinking maybe I’m still pregnant but I’m scared to go and find out if I am or not. If anyone who’s had a miscarriage did u still have a little bump ?
