Breech baby?

Br

How are you able to tell whether or not your little one is in breech position, aside from the doctors? I am 31 weeks, haven’t been to the doctor since I was 20 weeks for anatomy scan. Tomorrow is my first appt in weeks, to do my sugar test, and I won’t be going back in at all until baby is born. But, over the last few days, I have felt baby doing flips and rolling over extremely low in my pelvis, to the point that it’s very painful! I know it’s not lightening crotch, because it’s over my pelvis region, and 10x worse, lightening crotch is felt in the cervix. I know baby still has room to move around, but not sure if it’s something I should be too concerned about and bring up to the doctor tomorrow?
