FTM Movement Question

El

So, I finally figured out last night where my little one probably is. I’m 18 Weeks today.

I felt a hard lump on the lower left side of my tummy, around like the panty line. And then later when I was having my fiancé feel, it had moved to the right.

I’m assuming that’s my baby, but just thought I’d ask if this pressure I randomly keep having in that same area that sometimes feels like it’s moving across my tummy is my little one moving?

I know it’s not gas, I’ve never felt this before. Gas pains tend to be more painful for me, not just discomfort like this.

Also, here’s a bump photo💕
