preeclampsia with low BP???

anyone else struggle with preeclampsia but have low BP? my blood sugars are all in check and A1C is fine so the elevated protiens in my urine arent from that. I have had a few moments where my BP got up around 140/100 but I will say its happened maybe 3 times in the last month.... I have been in and out if the hospital with elevated protiens in my urine but while I'm there my BP is low. like anywhere between 117/65 to 95/42..... I thought high BP and preeclampsia went hand in hand but several nurses and doctors have said it can often present without high BP... so what else can I do to help keep it in check? I'm already on bed rest. are there certain foods or drinks I should avoid? or any other suggestions to keep my urine proteins low?
