20 week scan should I worry??

Avery

we had our 20 week anatomy scan today and our baby was a little jumping bean. after finishing, the technician left to go speak with the doctor after sending over the pictures. she came back a few minutes later saying she needed to take one more picture because "it didn't go through" after getting the image she needed, she said my scan was all done and I wouldn't need to worry about coming back. She made it seem like everything was all set.

fast forward a few hours and I get a call from the scheduling office saying they need another picture of the baby's spin, but for some reason, the doctor wants to wait for 2-3 weeks. that seems strange to me in that they would want to have all the pictures as close together as possible. I am wondering if they saw an issue and are waiting another few weeks to monitor it?? has anyone had a similar experience before??
