I'm very nervous!

So my dr hasn't been very informative at my appointments. I found out at my 36 week and 6 day appointment that I was having an ab over average sized baby. Dr only told me this because I brought someone with me. When I go alone he barely tells me what I'm measuring. Fast forward to my last appointment (38 weeks 6 days) under his breath I heard him say 42 when measuring my stomach. Also when he has been checking my dialation and effacement all he says is 1/2. So I decided to go to a midwife and get some more information because I was getting no were with him. I saw the midwife 2 days after my Drs appointment and she measured me at 43 weeks 2cm dialated and 80%effaced. I'm very nervous about having a larger baby. I'm only 5'7 and it's my first child. Is there a risk for my dr waiting so long for me to deliver?  He told me I won't go much past 40 weeks which is the 15th of October. But he has to schedule out 3 days for an induction. I'm scared I'm going to have a huge baby.
