Good question With DS i was induced so didn't really have pre-labour symptoms as such but i did get the runs when the drip was put in and contractions started.

This time round i have no idea what my body is doing! I feel like i've been in pre-labour since 36weeks! I've had loose poo's (sometimes pretty much the runs 3-4 times a day) for weeks and have been nesting like crazy this last week. Bub is engaged and ready to go and sooooo low (has been since 32 weeks!) but no labour yet .
I've been getting braxton hicks like crazy all through this pregnancy and in the last few weeks they've been coming 10mins apart for a few days then stopping. Very frustrating!.
Anywho i was sure i was going to go into labour yesterday because i just felt 'off' and had the runs...no luck yet tho..
