Ugh now I'm paranoid

I'm part of a group on Facebook for women with pcos. Someone asked a question about pcos and miscarriage and the admins, plus a few members jumped all over this girl, myself and another lady about it.

They kept telling the op how she needed to see a Doctor immediately because she wasn't on progesterone and she was going to have a miscarriage. I'm not on progesterone, haven't even seen a doctor because the earliest appt isn't until February. I explained this and was called stupid, and told I was going to lose my baby.

Now I'm freaked out about it. I was doing good not considering the possibility of miscarriage but now I'm all freaked out.

Any suggestions on getting this out of my head?
