I went through this exact same thing just four months ago with my second baby. I first went to a chiropractor in Aurora to have her try the Webster technique. She puts pressure on your lower back to try and open your pelvis area so that the baby might flip on its own. I went four days in a row, but I had one stubborn little baby and she didn't flip. I had the external version scheduled already for the following week; I just wanted to try that way first. If you want her name, let me know. She did a very good job and I loved her. Just some babies don't flip from the Webster. She's on North Eola, close to 88. You should find a chiro who specializes in peds and is trained specifically in this method if you don't go with her. I also tried the methods of placing a frozen bag of veggies on my belly to try and make her move as well as playing slow country music on headphones and moving them down so the baby might follow. Again--a very stubborn baby who wouldn't go for that.
So I went to Edward Hospital for the version at 38 weeks and it was successful. It wasn't incredibly painful for me, but it was VERY uncomfortable. I researched the procedure online beforehand and some women said it was too painful to continue. I think it is different for each person. I had to breathe through it like intense contractions, but I tried to remain calm and focus on her turning. They gave me a shot to relax the uterus so that helped some. The main thing is trying to keep your belly relaxed because if it's too tense, it goes against the turning. I wanted to avoid a c-section if possible, but certainly would have had one if it warranted it. My doctor did a quarter turn, checked the baby's heart rate and then asked how I was. She did that four times, each time checking the baby on the ultrasound. If anything was causing stress to the baby, or if it was too painful to me she told me she wouldn't continue. We went in that day with the possibility of having an emergency section, but luckily she did flip. It took about 7 minutes for the procedure.
I stayed an hour after for monitoring and then went home. I went into labor on my own 10 days later. I did have a nurse friend tell me not to bend over once she flipped to reduce the chance of her flipping back. I did this. It wasn't easy not bending over for 10 days, but I really didn't want her to flip back after all of that:-) They also gave me an abdominal binder to help things stay snug. She also said to try to avoid sleeping flat. It was too uncomfortable in the bed so I slept in our comfy recliner for those 10 nights at a partial recline. It was a lot better than the bed and being propped up on pillows.
My baby was almost 10 lbs at birth so maybe she was just pretty snug where she was, but it was a successful procedure.
I was very nervous, too, but my doctor did a great job and it worked out. Good luck!
