Pregnancy Pointers/Recommendations?!

So I’ve struggled with PCOS for as long as I can remember and I honestly thought I would have to try really hard to get pregnant. On Monday I finally got my BFP and I’m super excited and happy but also nervous because I want to make sure I’m doing everything I can to be as healthy as possible for my baby. Does anyone have any recommendations on ways I can boost my chances of a healthy pregnancy? I would also love any prenatal vitamin recommendations! Thanks so much 💗
