170 BPM normal po ba sa mga nasa 1st trimester pa lang? 12weeks and 3days po ako .

Mama, I understand your concern! But please check with your OB as soon as you can, heart rate readings in pregnancy can mean different things, and they need to see the full picture with an ultrasound. A few of us mums have worried about the same thing, but it's really best to let your doctor assess it properly so you can have peace of mind. Don't stress too much in the meantime, okay?
