I started my period when i was 13 and for 3 years my period was irregular. I got it every 2 to 3 months and then bled for 2 weeks or so. I went on the pill at 16 and stopped around 18 and it made my periods come at a normal pace. I took my last case for now in december and since the end of decemver i haven't gotten my period. I'm not pregnant. This is something that has bothered me for a while. Can anyone help me figure out why or what i should do or who to talk to about getting it figured out? It honestly really bothers me.
