Inducement?

Beth • 20🙋🏼 - engaged 💍 - ballet & dance 👯 - pregnant with my first 👶🏼 - my baby boy is due 10/02/2016 👣💙
I'm currently 20 weeks pregnant, I had three operations start of the year all keyhole and one was a abscess removed from my belly. The scars are hurting me and I've already been prescribed co-codomol because they are hurting me, I was thinking if I could get induced at 36 weeks or later? I'm only small and size 6 so I'm massive already, think they would consider seen as it was March and feb they was done? Thanks :)
