Well that's it really. Should I be worried? I have had a very busy day - I am a theatre nurse so have been on my feet all day for a ten hour shift and it has been manic. Just sat down for my dinner and am getting these sort of mild period type cramps in my lower abdomen and lower back. Don't think it's BH as my bump doesn't feel hard at all, but I'm quite well covered (fat!) so not sure if I'd be able to tell? Any thoughts?
