If your doctor is planning on doing a C-Section they usually schedule you around 34 weeks to have it done in your 39th week. If the doctor didn't say anything to you about it then you should still be fine for a vaginal birth
I think High is a good thing... much better than a low lying placenta.
If ny forward you mean anterior, there isn't too much trouble with that... just remind the doctors if you have a C section. Anterior placenta can be cut in C section of not located first.
I'm sure natural will be the best and perfectly safe either way.
