I don’t know if its PCOS

Hi, I’ve been struggling with this for a while. I honestly didn’t know it existed. When I was 17 I had two ovarian cyst on my ovaries. The doctors assumed it was stress. They put me on estrogen pills and they went a way. Once that was over with. I noticed darker hair around my neck and the sides of my face and my upper lip. Even down my stomach. I’ve tried everything to get rid of it. My mother likes to point it out. A lot... my weight always was the same. Never could loose it. Cuz oh I could gain it. A few years later my periods were SUPER off. Before they were never on time. But close enough. But this was different. I would have one for a week. Then I’d miss a month. But then I’d have one for two months straight. Then I’d stop a week and bleed again. The doctors had no idea why so I was given birth control options. After a pregnancy scare at 20 i wasn’t against it. (I don’t know if it was a miscarriage. Doctors said if it was I wasn’t that far along to really tell for sure.) I was told to pick a birth control. So I picked Nexplenon. The rod in your arm. Yeah. Slowly started to hate that. Gained 30 pounds in 4-5 months. No change in diet. I’m up to 45-50 extra weight gain. My cup size went from a DDD to an F. Ugh I hate. I’m glad I’m getting this thing out of my arm this week. I’m worried that if I have PCOS would birth control make it harder to have kids? I’m 22 now and my boyfriend and I are talking about marriage and our future and I’d love to have the option for kids just not right at this moment. I’m kinda of at a loss of what to do. I don’t want to go back to birth control. I want to try and lose to weight I’ve gained. But that’s always been a struggle for me. Do I have PCOS? I’ve tried to talk to doctors about it. But they seem to brush it a side. I just want to know what’s going on with me. Any advice???
