Bleeding at 10 weeks

Normal lang po kaya ito? Last ultrasound ko (oct 1) Supposed to be 7 weeks preggy but sabe is baka earlier pa because sac palang nakkita and wala pa heartbeat. Wala pang exact na sinasabi si OB kung ilang weeks na talaga. Nagpaschedule na ko for check up tomorrow. Nagwworry lang din talaga ako. #firstbaby #1stimemom
