Breech baby

My 5th pregnancy and she decided to turn breech after already being in the correct position. I'm thinking she may have turned again, but I'm a definite plus size Mama and can't feel what is where on her. I'm due the 18th.

Anyone have their baby turn during labor? My midwife wants to do an ultrasound Monday to see where she is and if she's breech she wants me to get an aversion and then directly pop my water.

I'm not ok with either of those. Baby comes when baby is ready. It's how I've done all of mine.
