i think too early pa po para makita si baby. usually po thickened endometrium palang or sac palang sa ganyang time or age of gestational. wait for 2 weeks for repeat ultrasound po. while waiting, don't be stressed & have a healthy diet & lifestyle po muna wag din po muna mag pa tagtag.
Bumalik na lang po kayo as advise. Don't stress, sobrang aga pa po kayo nagpa-ultrasound. Karamihan nga at 5 weeks, no heartbeat pa kaya nakaka-praning rin ☺️ Better to wait po mga 7 weeks para mas sure na detected na rin ang heartbeat 😄
