I think I might have pcos

Before I got pregnant and had my daughter, we had trouble getting pregnant and I got tested and nothing, well after I had my daughter last year my period started coming back normal and then they started to go from on time every month to 3 days, a week and then a month late, and then I noticed right before I start I will get a pain in my right pelvic area, so I went to the doctor and I was going to get help getting pregnant again but we changed our minds to get on the pill and get my period back to normal and then start trying, well I had to see a different doctor that day and she asked me if my periods are regular and I said no and then she asked if I had PCOS and again I said no, then she said she "thinks" I have somewhat of pcos, and I was thinking why couldn’t you set up an ultrasound to see if I do or not just to see what’s really going on but no she didn’t. She wants me to come back to see how my blood pressure is doing on the pill because if it still kinda high she have to take me off of birth control.

I have noticed I gain a lot of weight, irregular periods and hair underneath my chin.
