I'm 15 and I usually get irregular periods. They usually come about every other month, and last for around a week. The last one I had (besides for now) was the beginning of February (it's halfway through May now). I got this period the first week of May super light and only for some of the day. 15 days ago today, it got really heavy and hasn't stopped. I made an appointment with the doctor, but the closest date they had is in 3 weeks. Anyone in a similar situation or knows what to do? By the way, I'm not and have never been sexually active.
