I have 2 friends who delivered twins 5 weeks apart.

The first 2 kept switching positions going top to toe - kicking eachother in the head! At 37 weeks they were both head down ready to go. They were both born vaginally at 37+4 with an epi.

The 2nd 2 were born at 32+3 weeks & were also delivered vaginally. They were taken to Sydney where I think they decided on a vaginal birth as it is better for the babies lungs to be born that way.
I don't know if she had an epi or not.

My 2 girls were over a week over due, but my 3rd was 2 days before the due date. So there is no guarantee that you will go over again. Especially with twins. I think they have a habit of coming a bit earlier.

Don't stress too much. These things are not definetely going to happen. It's a risk. It may be higher than it would be with a singleton, but it's still a risk that could happen in any pregnancy.

Talk to your OB, & MW & anyone else & find out as much as you can.
