BP fluxes, preeclampsia, is it too low?

Sarah

I was diagnosed with preeclampsia last month. at 28 weeks I'm now 32 weeks. I was given a prescription  for Aldomet 250 mg. twice a day. my BP was staying around 135/80 for the last few weeks then last weekend it started getting high like 148/90 then a few days ago it started dropping like 110/65. it keeps jumping up and going back down. it kept doing fluxes like this the night I was in the hospital and discovered I had preeclampsia. is it dangerous for my BP to drop too low. I know a few weeks ago my Doc mentioned we dont want my BP getting too low since it was used to being on the higher side with most of my readings he said ideal while  being on meds is around 130/80. I had a doc appointment on friday but it was at a different facility in the network of the clinic I normally go to due to my clinic not having available appointment for my ultrasound and NST that day. I mentioned it to the nurse but she didnt seem concerned and I never actually spoke with the doc that was in that day the nurse relayed info to and from him. my next doc appointment isnt until Tuesday. I've included a pic of my BP reading so you can see how they've been fluctuating.
