A question for the ladies? And mature gents!?

I do get annoyed about the mess in my room but for some reason i dont get the 'urge' to clean it. Infact i always get a BAD migrane the day before (like Amanda previously said) and i dont get any headaches any other time of the month so i know that means i am about to start. Once that starts i tend to veg out for the next 3 days, i only get pains for the first 2 days of my cycle then i am fine so can carry on as normal.
