Ay, 110bpm is actually perfectly normal for 7 weeks, pero hindi talaga pwedeng malaman kung boy or girl based sa heart rate lang! A few of us tried guessing that way with our pregnancies and lagi kaming wrong, haha, honestly ang heart rate ay almost the same for both boys and girls at ganitong early stage pa lang. The old wives' tales about heart rate aren't really reliable, kaya better na maghintay nalang ng 18-20 weeks for the anatomy scan para makita ninyo talaga! Congrats on your pregnancy, mama!
