Preventing Cholestasis and Preeclampsia in Subsequent Pregnancies?

Hannah
Hey y'all! So I'm really seeking advice/information here. I was diagnosed with Cholestasis and Preeclampsia at 33 weeks with my first pregnancy. I am now pregnant with my second just under a year after delivering my first. Does anyone know how to lower your chances of developing either of these conditions of pregnancy with subsequent pregnancies? I'm doing a ton of research, but I would also like to here what other moms might know! Thank you so much for your help. I'm due 10-4-17 with baby #2 and I'm wanting to go for a birth center birth this go around, if at all possible 😊
