I think I have PCOS 😩

Okay so I’m about to be 21 in March but that’s irrelevant lol anyways I’m not sexually active yes I’m overweight and I haven’t had my period since December so I’m freaking out and I’ve talked to my mom and she thinks I have it bc I have some signs. She knows the signs bc she has PCOS. I’m over weight, I’m growing hair on my chin and I tweeze it and it comes back fast. I’ve looked up some more signs I have and I’m freaking out I’ve never been to the lady dr but I plan on making one this week. I’m scared 😞
