I'm 15. I got my period when I was 13 (about 2 months before my 14th bday) and I haven't had a period since November 2018. I haven't been too sexually active. (DEFINITELY not preggo +plus I had a test. ). I have popped the cherry by masterbation when I was 14. I'm scared something might be wrong and I have an appointment to go check it out. My friend told me her period was irregular (like months between) but she got on birth control and then it became regular. Any answers or possibilities of something?
