Mama, I'd really encourage you to check in with your OB right away, especially about baby's position and the heartbeat, para sure lang na everything is okay, okay? At 5 months, baby moves around a lot pa, so positions change, but it's best to let your doctor explain what they're seeing during the ultrasound. A few of us mums always ask our OB directly kung may questions kami about baby's position kasi sila talaga ang may expertise. Don't worry too much, but don't wait din, quick call or visit sa clinic is best!
