Just curious?

I'm 39 weeks pregnant and I've had my few shares of head aches here and there nothing to big or obnoxious. But since last night around 9pm till now my heads been hurting and it hasn't gone away at all or simmered down. Is that normal? I'm a first time mom and so I'm a little concerned. I'm so uncomfortable right now because of my headache but also pressure and pain here and there. Am I worrying to much over nothing?
