Aw, alam ko ang worry mo, mama, these things can sound scary pa lang at 23 weeks! But honestly, you really need to talk to your OB about this, especially about placenta previa at breech position kasi may things they monitor closely as you progress. Many babies still turn on their own, and placenta position can change too, pero your doctor lang ang makakasabi ng tama based sa ultrasound mo. A few of my mum friends had similar concerns mid-pregnancy, pero sobrang importante talaga ang regular OB checkups para ma-monitor properly. Don't panic muna, just make sure you're seeing your doctor regularly at ask her lahat ng tanong mo, okay?
