My first pregnancy, my little girl was breech the whole time. You can Google spinning babies. Nothing worked for me, but for some people, it works. My Dr offered to turn her at 37 weeks, but it scared me to try. The success rate isn't that great. My friend had tried when she was pregnant with no success and thought it was painful.
Your doc should offer you a chance to turn baby or get c section. Went in for my 38 weeks check up when I found out, doc said she was head down but my bf insisted on ultrasound that's when we found out she's breech, so she offered to turn the baby or have a scheduled c section and of course I choose turning first. Hope it helps Goodluck
