Little freaked out

So I just got paperwork back for my leave of absence for work and it states Nephrolothiasis, renal disease, high blood pressure and high risk factors for why I am on leave I do have a history with kidney stones / infections and high blood pressure but the renal disease is new to me and it's scary I'm 30 weeks pregnant and so far we are good I have worked so hard to have a healthy pregnancy part of that was reducing stress and going on loa early on but this is stressing me out a bit i just want to be healthy for my baby girl my husband and for our families future
