Worried?

So I got cleared recently from GD. Today I woke up feeling fine. Took a shower (ended up puking thanks to mucus), but felt fine. I sat down with my kids and ate breakfast then did the dishes. After a while I started getting light headed and short of breath so I sat down. Started feeling fine got back up to continue and felt lightheaded and short of breath again so I sat back down. Felt fine (rinse and repeat) so I went to the bathroom then decided I was going to take my blood pressure. I was a CMA and still have my blood pressure cuff and stethoscope so I took it and it was 150/110 so I repeated it a couple times and had my husband do it as well and we were getting the same thing. I usually never run over 120/80 (I have consistent low BP my typical BP is 90-100/60-80) I'm not sure if I should be worried or not? I've never had protein in my urine either. I didnt have this with any of my previous pregnancies either as well.
