I just came back from my appointment. I've put on 3 lbs since last week (and 4 lbs the week before that, what the hell?). I am 2 cms dilated, 50% effaced, but everything was so high up. It felt like she was checking my throat through my hoo-ha, seriously.
I don't know if those 2 cms 50% amount to anything, since it's my 2nd baby, but I was quite excited to hear it.
