Ang normal fetal heart rate usually around 120-160 bpm starting sa second trimester, kaya 110 bpm ngayon at 7 weeks ay maaaring slightly low, pero honestly, best to have your OB check this during your next appointment para ma-monitor properly! A few of us mums went through similar worries at early pregnancy scans, and sometimes it's just the timing ng pagcheck or position, pero peace of mind talaga if your doctor confirms everything is okay.
