Possibly have PCOS

Hi, so I haven't asked my Dr yet, was looking for some insight before I do so...

Some background.. I just turned 28, I have 6 kids. I had my 1st at 17. Before I got pregnant I was about 125lbs 5'7. I had all of my kids pretty back to back. I lost all of my baby weight immediately after my first. Well, I got on the depo shot & was on that for like 9 months, gained 40lbs, I was miserable. Then shortly after got pregnant with my 2nd. After having my 2nd I lost all but 10lbs. Got pregnant like 4months PP & also lost all but 10lbs... each pregnancy I seemed to have kept an extra 10-20lbs that was like nearly impossible to lose, no matter what I ate, how active I was...

December 2020 I had my 6th. She'll be 11 months tomorrow. I completely stopped breastfeeding at 9.5 months. I haven't had a period yet, my face has been super greasy even after I wash it... I'm the same weight I was when I gave birth to her... which was 235lbs. With my others I was on the pill before getting pregnant, I haven't been on the pill because I wanted to breastfeed my daughter & I didn't want anything to chance decreasing my supply....

So I was wondering if it's possible to have PCOS. I cannot lose weight. I can't. I have exercised, I've tried counting calories, watching what I would eat, only drink water (which I've always done, I'm not a pop drinker), I don't really like milk so I don't really drink that...

I just don't know what's wrong with me that I can't lose weight... I feel disgusting
