Oo, normal yan sa 9 weeks! A few of us moms had the same worry, pero ang baby's heart rate sa first trimester ay faster talaga compared sa older babies, usually between 150-180 BPM, so your 182 is totally within range. Since your OB already checked and said okay, you can breathe easy na, doctors see this all the time and they'd definitely flag it if something was off. I totally get the anxiety, pero trust your OB on this one; mas worried kami usually sa later ultrasounds kung may changes siya, so for now you're good!
