38 weeks headache and feeling sick

I know these can be normal pregnancy symptoms but I havent had any headaches or really been nauseous at all. Last night I got a bad headache that lasted for about 3 hours but went away with tylenol and rest. I was feeling a little short of breath and baby was moving around like crazy.

Today I am feeling very nauseous and just generally off. Do you think I should call my OB or just wait it out?
