Is it normal to get really bad headaches constantly while in your third trimester?

They go away with sleep but still come back

if they don't go away with sleep or Tylenol definitely bring it up with your dr as it could be high blood pressure

Yeah, mine started a week and half-2 weeks ago and I get them on and off throughout the day or sometimes just once a day.

I do just started last week or so get them at least once a day.
