can’t see my doctor till Monday!

Hi guys, I’m 17 weeks pregnant tomorrow and

I’ve been having mild-severe headaches for the past 3-4 days now

I know it’s slightly common in pregnancy due to hormone changes , dehydration, caffeine reduction etc etc

They come and go every few hours.i know I’ve been low on how much water and food I should be having but I’m not sure if I should just wait till Monday when I can see my doctor or if I should go to MD now and get checked ?

Or if somebody else has experienced the same thing
