I was just about to post on here about period type pain too! Not at all wanting to hijack your thread but.. every night between 6 and 7:30 without fail I have the most excruciating period type pains. Lying down makes them even worse! They come and go in that half an hour, quite like contractions but around about 7:30 they are gone!! I did get them again this afternoon too.. but only for about half an hour! Are you ladies getting them regularly or do the pains come at any time??
