The pill🤔

Okay, so this morning I woke up, feeling very sluggish and I had to go to school, I walked into the bathroom and changed my tampon and I used an ultra(the biggest). So I felt fine and I stood up and then all of a sudden my bathroom looked like a murder had just taken place, i was freaking out, and had to stay home from school today because of how intense the bleeding was, my mom was talking to me about getting on the pill, and so have I, I’m 14 and I need some help to figure out what to do!!! Thanks xoxo
