It's my 2nd pregnancy, my first son is 8 y.o., so it was a while ago. I think it was much easier the first time though. Now I'm 31 weeks and get tired pretty much a couple hours after I wake up - really tired, and have this strong pulling sensation in my belly, very unpleasant. I also can sit in a chair for a long time, because I feel like everything in my belly gets really compressed. And finally, I'm constantly gasping for breath... Anyone has similar symptoms? Do they mean anything, like that labour is imminent?
