I am 18 and was diagnosed with PCOS when I was 12. I wasn’t having periods but every 5 or 6 months for 2 days. And I have struggled with losing weight since I was a kid. I never have rate horrible. I always eat healthy and exercised a lot. i played 5 different sports. The first meds I was placed on was Metformin. It helped my periods a little to have them every 4 or 5 months but it stopped working, even with uping the dose. Then I got diagnosed with chronic migraines which suck butt. Within the 4 years I gained a lot of weight and I stilled played sports and exercised. I was placed on BC, Sprintec, to start my periods again which it has. I have a period every 3 months but I also have break through bleeding every 3 weeks. Has anyone had problems with their weight? With break through bleeding?
