headache 36 weeks

M
I have had high blood pressure since 29 weeks. Been on medication and it's been perfect..I go for stress tests 2 times a week. I just had one at 3:30 today. Got home and I started to have a slight headache. Over the last hour it has gotten just a little bit worse but nothing too bad. Lights don't bother me or anything but I can still feel a small headache. Is this something to go in to emergency for? Or is the type of headache supposed to be pretty severe? I read online it's like a migraine..mine is no where near that. I'm most likely going to go in just to be safe..just looking for some insight on this
