These headaches are due to the hormones cursing their way through your bloodstream and they should start to settle down by about week 20. Keep drinking lots of water and rest as much as possible with a cold compress on your head and back of your neck and of course panadol when needed.

I havent been pregnant yet but I got these same headaches when I went on the pill when I was 17. The doctor told me if I had them while I was on the pill, I would probably get them during pregnancy too so I guess I also have this to look forward too (hopefully very soon).

Hope they pass quickly for you .....
