Aww mama, I totally get the nervousness, first ultrasound is so exciting and scary at the same time! The good news is your PT is positive, so there's a very real chance baby's in there na, pero I won't sugarcoat it, best talaga na marinig mo directly from your OB bukas kung anong makikita nila on the scan, especially kasi may history ka with that cyst so they can check everything properly and put your mind at ease. Rooting for you so hard, update us after ultrasound, oks?
