I have benn suffering from PMT and very noticeably over the last six months, probably when I realised what the hell was wrong with me.
I am basically the womean from hell, extreme anger frustration, aswell as very heavy and painful periods.
I am not on the pill and preivoulsy had been on the pill for many years prior to having children , so periods wee not an issuue , everything was OK.
Since DS2 body has been up the spout., going back on the pill didn't agree with me and I didn't really want to go back on anyway.
When I realised what my problems proably were I started making a note of when all the symptons started to when I wnet to GP I could tell her excatlt what was happening.
During those months I tried Evening Primose etc but it didn't do much for me.
When I went to the GP she said it was lack of progestogen and prescibed me tablets to take betwenn day 19 and 26 of my cycle.
I have taken them for the last two months, my periods are less painful and not so heany and the mood swings have easied off although not completely, but it has helped.
I would say most of us fell shit at the time of the month but probably more so when under stress, like work or Partner away and delaing with children.
DH seems always to be away when its that time helped hasn't helped matters.
The tablets are helping . Go and see your GP and if your not happy with him cahnge him if possible.
Good luck
