High blood pressure

So I checked my bp today and it was 168/100!! Then did it on the other arm 168/92..I'm supposed to get at least 3 readings this week I've been on aspirin to help with the bp and it's been good up until last week! I've been on aspirin to help with the bp I'm almost 36 weeks...oh and on Monday when they checked my bp it was 152/80 then waited and checked again 148/80--- I'm assuming this is kinda high I had problems with high bp with my last pregnancy and had to go in early hopefully tomorrow my pressure will be better!! Anyone else having problems with bp?!
