WHY every time of menstruction, i get headache?

I sometimes get headache, too. Are you very thin ??
If you are, I think you may not get enough nutrients or exercise so you get headache every time during menstruation. Because the blood circulation in your body is not good, so blood may not always reach your brain to provide oxygen to your brain cells during menstruation and you will get headache.

I had the same problem before, the doctor said that is because of the change of the hormone's level. He said that is natual and noting can help. But after I try the Chinese traditional " Pak Fung Pills" it become OK. Any brand that's made in HK. One or two days before the menstruction.
