Charlotte's turned...again

Well the head down position was short lived. She's been breech up until last weekend when Mary was here. She turned last weekend to head down and I was all excited thinking no c-section (after already having 2 natural births a c-section is NOT what I want), maybe because I was on the floor crawling around playing with Jack and sometimes that position helps to turn the baby. I never thought feeling hiccups "way down there" and kicks in my ribs would be such a great feeling! Although unintentional I was very happy it happened up until a couple nights ago when she turned back. I can now feel her little head up really high between my ribs and I feel as though I am squishing her little head every time I sit! I have a dr appt Monday. I know I still have several weeks for her to turn but am still nervous. If she has not turned by week 37 I think my dr will do a c-section sometime that week because she'll be out of town for awhile and doesn't want me to go into labor on my own. There was also talk of an external version sometime in week 36 or 37 if she has not turned by then so we will see.
