Baby measuring small

Evee

Hey there everyone!

I wanted to know if anyone experienced their baby measuring smaller during their first US.

Per my LMP im 7weeks6days. When I went in for my ultrasound the baby was measuring 6weeks2days.

The baby does have a heartbeat and the Doctor didn’t seem concerned, but he wanted me to come back for a 2nd ultrasound in two weeks to check baby again. Also turns out im very anemic so I started taking mega food brand blood builder supps.

How was your experience with baby measuring smaller?
