Mama, kahit may strong heartbeat, the change in movement + pelvic pressure at 29 weeks needs a quick check with your OB, please don't wait, call them today or go to your clinic, okay? Better safe than sorry, lalo na at iba-iba ang feeling mo ngayon. You're doing great checking with the Doppler, pero your doctor needs to see you in person para sure-sure lang. Sending you calming energy, second babies can move differently sometimes, pero let the expert confirm!
