I've always been prone to headaches. For around half a year now I experience them in relation to my cycle. I often have a headache starting the first day of my period that develops into a migraine on the 3rd to 4th day. I'm in a lot of pain and very fatigued during my period, so anything I can do is sleep, but it doesn't really help.
I try to eat, drink and sleep enough because not doing so triggers my migraine on top of my period being a main trigger.
