10 weeks but no heartbeat

Good day! Ask ko lang if possible na wala pang heartbeat si baby kahit 10 weeks na from the last menstruation? After transvaginal ultrasound, compatible si baby for 7 weeks and 3 days of age. Meron ding minimal subchorionic hemorrhage. Thank you po sa mga sasagot. Sa monday pa po kasi ang check-up with OB..
