Uy, congrats! Yes, it's very possible na buntis ka talaga, kung consistent positive ang PT and blood test mo, that's a good sign na may pregnancy hormones ka na, kaya hindi siya false positive! A few of us moms got positives super early din, bago pa mag-miss ng period, so you're not alone dito. Your OB is right na too early pa for ultrasound, kaya siguro better to wait by end of August para makita na talaga sa TVS, ang haba ng antayan, alam ko! Just take the vitamins she prescribed, stay positive (literally lol), and follow her advice para sa check-up toward end of month. Fingers crossed for you, mama!
