Swelling pic maybe TMI xx

Kate • 29 - 2ectopics now proud mama of 10yr old & 6mth twin girls xx
I've had my BP rise from a usual 100/60 to 134/87 and started with this disgusting swelling called pitting edema - when I press it, it takes upto ten minutes to pop back :(
 I have hospital at 10.30 tomorrow (UK time) to check blood pressure again if it's risen again they may deliver the twins :/ xx 
I do hope it's not the start of pre eclampsia :(
