Getting headaches and feeling funny

Kelli

Every afternoon about 5pm I've been getting headaches and I feel funny, I'm 15 weeks tomorrow, I'm not sure what I can do to fix this, I tried eating some jelly beans in case I needed a sugar fix that just made it worse, I tried not eating anything sugary no difference, I don't think it's dehydration, is it just a hormone thing?

Any suggestions?
