high bp?

Brittany
So last night my feet had started to swell more than the normal and have pretty much stayed swollen they went down a bit after not doing anything all day which drove me crazy but I have been monitoring my bp and it's been anywhere from 133/80 to 153/92 since last night. I haven't had any headaches or rib pain and I haven't peed protein ever. And the doctors have seen my bp at 138/88 and just said to watch out for headaches. When should I be concerned about swelling? My last dr appointment was Wednesday and my next one is Wednesday the 21st which is the day after my due date.
