Do you have a pressure type feeling down below? Do you feel like you have to perch on the edge of the chair/lounge? I'd definitely keep a close eye cos my last labour started with the AF feeling like you're describing. That's not to say that's what is going on with you though. Are you having any tightening type feelings across your belly and has bub dropped at all?
