If you measured large, how much did your baby weigh at birth?

Baby is currently measuring a full week ahead and in the 80th percentile. I have never had a full term baby (DS- 34 weeks and DD- 36 weeks) but I will be on progesterone till 37 weeks so I will probably make it to 37 weeks and change maybe 38 weeks. I'm nervous about pushing out a big baby... I'm also super petite..
