today I had started my period for my second time, and I had a really heavy flow and I got worried but I didn't tell anyone. And today after school I went pee, and there was this chunk of stuff that was squishy and it was smooth (I didn't see any bumps) and I got scared because I didn't know what it was and it was kinda big, so does anyone know what it is??? Plz help I'm only 12..... Thank you
