I know plenty of people who've had regular BH like this but it wasn't labour. But then I also know of women who've not realised they're in labour.
I'd call your mw and see if she can come round and assess you. Also I seem to remember that if it's just BH then having a warm bath will make them go away. If they're real contractions then the bath will make them more intense. Worth a try!
Frustrating is an understatement TheDetective. I'm the same... since 36 weeks. Was admitted into hospital at 36 who thought I was in early stages, made me paranoid as I was have so many BHs which is worrying if VBAC for the scar apparently.
I think because DD1 and DD2 were both early I expected this one to be too...
Hope your little one arrives soon. Is it your first? I'm hoping I'm going to be so pleased when I do go into labour it'll keep me in a positive mood!! I've already warned my parents that if I call in the middle of the night (to come and look after DCs) then they might get a cheer down the phone!!
