Have discovered I have appalling PMT since I had an IUD put in (prior to ds and dd was on the pill for 15 years so wasn't having 'real' periods). I am talking terrible mood swings, inability to control my temper and aggressive irrational behaviour. I have been close to hitting my children (2.5 and 10 months). My dh knows my period is on its way well before I do. Can anyone offer any advice? I am really scared I might do something really bad although have not spoken to the GP yet.
