New Mom to be and slightly freaking out

Hello! I just found out yesterday that I am pregnant I called and made my first appointment and they estimate me to be around 8 weeks along. I’m starting to get a bit nervous because most of my symptoms have begun to come and go rather than like they were and I have PCOS so any little thing freaks me out because I’m worried something will go wrong or something will happen. Any tips on how to not let that stress me out so much or any experiences with pregnancy and PCOS? Thank you!
