No, absolutely nothing in hindsight. I've been wracking my brain trying to think about it, too!
This pregnancy, I'm actually having some "hmmm..well, in hindsight..." moments. I've been having lots and lots of strong bh cx's the last several days (never had this before with any of my previous pregnancies), loose stools today, swollen feet (but just my right one, weird). Dh thinks I'm "looking ready" and he doesn't remember that with the other ones. I keep telling him not to get his hopes up! He's also not leaving me alone for long - he's thinking this labor might go really fast this time. I'm not so optimistic!
