Movements!

When was the SOONEST you felt movements with your second/third baby??

Tell me it’s possible to feel at 8 weeks...I’ve had a ton of gas bubbles lately and I know this was NOT gas. Just once last night I felt a tiny movement when I laid down and then once again tonight I felt the exact same thing in almost the same spot. I also had an ultrasound yesterday and this movement was in the same spot the U/S tech found baby! I know it’s crazy early...but please tell me I’m not crazy??
