Congrats sa buntis, mama! At 5 weeks, usually you won't see much on ultrasound yet, maybe just a gestational sac, and heartbeat is harder to detect this early, so don't worry if doc says hindi pa nakikita clearly, totally normal yan, kaya better to wait another week or two para sure na makikita talaga natin. The timing of when baby's heartbeat shows up varies, but it's usually around 6-7 weeks pa, so next week might be a bit early pa but worth asking your OB kung okay na ba sya makita or if you need a follow-up ultrasound, because peace of mind matters din!
