I'm 32+3 and have felt tightening's for a couple of weeks every now and then. I had the m/w this morning who when feeling my tummy said ooh your having a tightening. I said i'd been having them but today i've been having more than normal and have backache. they don't hurt really but they make me stop what i'm doing and stand straight and really know it's happening. they seem to last about 40 seconds to a minute then go and come back?
Don't want to ring and be a over reacting as am sure it's fine but what if it is labour?!?
