Uy mama, palpitations during pregnancy can happen, pero if you're feeling it strongly and it's been happening for days, please check with your OB right away, better safe than sorry, especially when it comes to your heart!
At 9 weeks, ang baby's heartbeat ay napakaliit pa to hear yourself, so what you're feeling is most likely yours, pregnancy does increase blood volume and heart rate, kaya normal na may changes, but your doctor needs to rule out anything else just to be sure. A few of my mom friends experienced the same thing and their OBs gave them peace of mind agad after a quick check. Wag mag-antay na, call your clinic today, okay? You and baby need to be safe.
