2nd trimester headaches! I had them awful with C and lightly with A. Mw told me its just hormones. Not that that helps but it is normal. All i can sggest is as much sleep and fluid as possible. Drug free things that help are 4head sticks on the temples, forehead and back of neck or the gel pads you stick to your forehead were a godsend for me. I also use tiger balm if i dont have a forehead stick but its very strong so use sparingly or you will stink and find you can see for the tears in your eyes from the fumes.
