Headache/nausea

Ive had a bit of a headache and nausea for two days and today it's turned into a migraine and blurry vision and nausea I took Tylenol this morning and it went away but now it's back my bp I have monitored all day it's been 122/89 to 130/88 lots of pressure in my bum and pelvic area and he's moving around good I'm 37-6. The dr said to go in and get monitored if I felt worse really not sure what to do I tend to be a bit of a hypochondriac.....maybe it's just a stress migraine it's been forever since I've had one I had my usual coffee this morning and had a pbj sandwich and milk and water and that's it all day I'm hungry now but it goes back and forth with nasuea. I had my last appt Wednesday and my protein was fine. All pregnancy I've had mild swelling and today it's the same no increase.
