Hey! very much the same boat, my DD is about to be 5 and I have banging headaches every day which isn't like me at all, I never get headaches.
I am meant to wear glasses for reading and stuff so if I get a headache I just shove them on and hope for the best. I drink a glass of water too when I get one, but to be honest that is all I do! I don't want to take too many paracetamol because I reckon I would need them all day every day during this pregnancy so I just don't bother lol xx
