Two different fetal measurements?

Mia

So last Thursday (7/11) I had an ultrasound to see our little Peanut 🥜

All is well and they said everything looks perfect, no problems. She told me Peanut is measuring 9w+5. Great, awesome! No problem 💜.

Well I'm headed on vacation soon, a very long journey and won't be back for five weeks, so they wanted to do a second ultrasound right before I left to do a test and to make sure all looked still well.

Peanut is still happy and healthy, even did a little jump on screen. Second ultrasound done today (7/19)

Then she told me Peanut is measuring 11w+1. I thought, that's a huge difference compared to last week. She didn't seem bothered by it, but I found it interesting...

Could I be pregnant with twins and they're measuring two different babies?! 😳 I dunno if they flipped the ultrasound screen for this one or peanut has flipped but they're facing different ways aswell....

Maybe I'm reading too much into it...
