Awful headaches that get worse with movement.

I’m 16 weeks pregnant and idk I think for about a week or two I’ve been experiencing terrible headaches. Headaches that don’t go away and get worse all of a sudden when I stand or move or do anything really. Like if I move the pain goes from a 6 to a 9 real fast for a few seconds and then goes back down. Sounds normal or should I worry? I was in the ER last night for something else ( cardiac related) so preclamsia has been ruled out.. anyone else experiencing the same?
