Not the only one at all. It seems I've had a headache everyday since around the same time too. My doctor prescribed me some other medication that was safe to take last time I went in that's helpful. Make sure you stay on your water intake!
I've had them every day since 6 weeks, but they have been getting worse since 12 weeks. I finally broke down around 15 weeks and went in for a migraine i'd had for five days that was affecting my vision. They gave me bitalbutal or butalbital, something like that.
I had TERRIBLE headaches between weeks 14-22. When Tylenol was completely useless, I used a cool compress on my forehead and then a warm one of the back of my neck. I also found that smelling Rosemary, lavender, and peppermint sprigs really helped. Good luck!
