I came on the day before yesterday, in the evening. That day I managed to get up early, and get loads done. Since then though I have just been so lethargic. I've been trying to get up early and have failed both mornings. I don't remember feeling this bad before, although it seems my periods are only just getting back to normality after having DS 14 months ago, ie, heavy and painful. It is just to do with my period isn't it?
