I saw my midwife today. Good news is that all the pre-term labor I've been having isn't doing anything to my cervix. I wasn't expecting it to because the baby is pretty high up. My cervix is high and closed, so that's a relief.
I'm up 23 lbs so far. I'm really happy with that because I only gained 18 lbs with DD and she only weighed 5 lbs 8oz, so I've been trying hard to gain enough this time. I'm measuring 36 weeks, so I think the weight gain is helping. He's already measuring bigger than DD was at birth (I know these measurements are only an estimate).
Otherwise things look good. I go back on 8/3 for my GBS culture and every week after that.
