I'm 17years old and I started my period when I was 12. They were usually pretty regular but a few months would skip here and there. I had protected sex although I'm not on birth control and afterwards, I didn't get my period for 2 months and I took pregnancy tests to know for sure I wasn't pregnant. I stopped having sex to see if my periods would go back to somewhat regular and I still skip a month or two and when I do get my period it doesn't last a week. Am I okay? I think I've only had about 5 or 6 periods this year and I'm low key scared
