Hi mama! Okay, first thing, please follow up with your OB as soon as possible para malaman natin kung ano talaga ang situation ng baby mo, okay? The fetal heart rate can vary depending on which stage ng pregnancy ka and kung kailan siya sinukat, pero importante na marinig ito directly from your doctor. A few of us moms have gone through worries like this, at ang best talaga is peace of mind straight from the specialist. Don't stress yourself too much in the meantime, but do make that appointment right away. Sending you hugs, and I'm sure baby is okay!
