Headaches! ?

Es
I'm 13 weeks and 5 days pregnant and I've been struggling with these gosh darn headaches for about a week now. They're on and off and really annoying. On a scale of 1-10, I'd say they're about a 4 or 5. Maybe 6. I don't wanna think negatively right away because I don't wanna scare myself. I have an appointment on the 6th and I plan on asking her about this. But in the meantime, is anyone else going through this? Is this normal? Or should I be worried........?
