love 🤰#1 👼🏻

Hi girls according to my Af late i am 1 month 16 days from my aF it was on 13 april 2019 ..

Now my question is when i did ultrasound last time before a week dr could not find a sac or baby .. then today i went he found a small dot which is shown in ultra sound .. i am using glow and Baby center app to know how many weeks i am .. i am 6 weeks 5 days but dr could not find how many weeks i am .. and he did Beta HCG it was positive with 1565 Ml ...

is this happen to anyone that baby didn’t show the baby in the ultrasound in early pregnancy .. or its just me 😔😔😔 i am very worried !
