Well last night I had stomach/back pains....it kept coming in waves... At about 2am it was getting bad enough for me to wake OH...and I was seriously considering phoning the hospital because we thought that something might be happening... Anyway I went to the loo.....and it turns out I just needed a really big trump how embarrassing would that have been if I'd have turned up at the delivery suite!?
Bless you I have had some bad wind experiences too- you'd better watch how many brussel sprouts you eat on Christmas day!
