Sac measuring behind baby

Katie

With history of chemical pregnancy and ectopic I had an early ultrasound. My first ultrasound I was 5w 4d. Heart rate of 111bpm. Sac was 6mm 4w 3d.

Had another ultrasound yesterday at 7 weeks. Ultrasound tech said everything looked great. But when I was reading over the specs I saw the sac seemed like it measured small. Heart rate was 131. Measured 6w 4d but the sac was 9mm measuring 5w.

They never said anything to me about it and I wouldn’t even know if I didn’t read the ultrasound so closely. The tech seemed really happy with everything.

Of course I then start googling and freaking out. Anyone ever experience or hear of the sac being smaller like this? I don’t know what to think 😔
