I'm not sure this is the correct community to ask, if it's not, please let me know which is best!
So, I'm 20 years old, but I haven't had a period since I was 16 or 17 years old, and I've never had irregular periods. I had been on birth control to help with cramps and terrible mood swings for a couple of years prior, but I stopped taking them for some reason I can't remember. About a month or two of being off of them, I realized I hadn't started a period since. I knew I wasn't pregnant, because I had never had sex, so I went to my general care doctor since he prescribed them, and talked to him about it. He must have said something along the lines of my period should be happening because nothing was wrong with me, because I remember asking why I wasn't having one of things were fine. I don't even know what tests, if any, were done. I wasn't referred to an ob/gyn or anything. After the appointment, I don't remember being told to make another appointment, or make one with an ob, or anything. So I waited. I waited months, even years. By the time I was 19, I still hadn't had a period, and had been put on share of cost and was losing access to my medications because I couldn't afford them, so I had just finished my last prescription of my last medication; Zoloft. About 2-3 weeks after taking my last pill, I noticed a few small amounts of light blood, and thought I was getting my period in the next couple days. But that didn't happen. The spotting stopped, and a year later, I still haven't had one.
My question, finally, is, if I was ever able to go to a doctor and fix whatever was wrong, if something is wrong, or just randomly started getting them again, would it affect my ability to get pregnant later on?
