That could very well be the baby. I felt mine at 9 weeks almost 10, but then again this is my third pregnancy!
I felt my babies around 12 weeks and I'm a ftm aswell
Thats when i first felt my girl move. And it felt exactly like popcorn popping!
If your instincts say yes, then I'd say it's most likely so! Some feel their baby a lot sooner than others, depending on how big you were before pregnancy. I started feeling the popcorn feeling at about 16 weeks, but I was also a little bigger to begin with, and I'm also a ftm, so I wasn't really sure what I was feeling. But sure enough during my ultrasound, I felt the same thing, and he was doing flips in my belly! Lol
I had tree losses I'm currently 11w2d and I feel that too I also think its my baby I still haven't had a scan waiting for appointment x
