Just found out there was a little protein in my urine, not enough to be preeclampsia but he said to watch my blood pressure, he never told me what was to high but I was looking online & it said 140/99 was high & he said if it got high to go to the hospital, can someone please give me advice on how preeclampsia works? & what to look out for??
