I'm 37+4 weeks. Yesterday i had a constant period type pain on my back all day. Wasn't too painful but enough for me to keep mentioning it my husband that things felt different. Went to bed as normal about 10pm and woke up at 2am with bad period like craps around the front which kept coming every 10 to 15 mins. Didn't sleep sleep a wink. I was then sick around 6am but went back to bed and have managed to get a few hours sleep since. Have now woken up again and the cramps seem to have settled but still have the dull back pain. False alarm or a sign of things starting? I'm not sure when I'm supposed to call delivery suite etc is it too soon or do I call and see what they say?
