I noticed my PCOS got worse after both my kids were born cuz my periods were all over the place and then they suddenly stopped and it freaked me out cuz I kept thinking I was pregnant and then it come up negative and it was stressful it literally I started losing my hair I stopped eating and I got told it was just my PCOS my testosterone levels were higher than my estrogen levels and they put me on birth control to stabilize my hormones
So I experienced this after my second daughter was born I found out I have PCOS which is not always the case it could just be stressed it could be hormones it could be whatever but I would definitely go talk to a doctor and get a opinion about it
