Congrats, mama! So happy for you! Based on your last period (Dec 16-20), you're around 6-7 weeks along na, and most OBs prefer to see you for your first prenatal around 8-12 weeks, pero you can call your doctor now para ma-schedule and mag-confirm ng dating through ultrasound. A few of us dito sa community, yung iba nag-start ng prenatal agad after positive PT para ma-ease the worry, so it really depends sa preference ng OB mo, pero wag mo nang pilit kung gusto mong makita mo ng malinaw sa ultrasound yung baby at heartbeat!
