If your doctor wasn't worried, then you shouldn't be either. That doesn't mean don't be vigilant and pay attention to the doc's instructions to take it easy though. Definitely rest and drink lots of water.Unfortunately back pain seems to be a common ailment of pregnant women. Yoga and positioning yourself on all fours might help alleviate some of your back pain (avoid squats though since your little one is breech, no need to encourage it further down). I'm carrying my second baby transverse (sideways) and it is much more uncomfortable than my first who was head down. So that might be contributing to your back discomfort. I think babies cause less discomfort when they are head down.As far your as baby being breech--have you looked at the website called www.spinningbabies.com. There are suggestions for encouraging a baby to get head-down. Also many OBs will try to do an external version around 37-38 weeks to move baby head-down before opting for a c-section.Did the doctor give you a handout on things to do to avoid pre-term labor? I had to go to the hospital at 24 weeks because I'd had 8+ contractions an hour for 5 hours. They gave me a list of activities to avoid and things to do to help prevent early delivery. (Things like, keep your bladder empty, drink 8-10 glasses of non-caffeinated fluids, preferably water a day, don't lie on your back, stay off feet as much as possible, and no sex or stimulation of nipples)No one, not even your doctor knows when your labor will start, despite their experience. With my first pregnancy I had a show on a Friday morning but no labor, and was told by my doc that I'd probably be back that night. I didn't have my son until the following Tuesday night. It was a very long weekend.I've known several girlfriends who were 1-3 cm dilated 4-6 weeks before delivery. At 33 weeks your baby has great chances outside the womb. Just relax, enjoy the last few weeks of pregnancy and take good care of yourself.
