Just a slightly funny story

I'm 19 weeks pregnant and I Was in the T-Mobile store the other day with my husband and daughter. We were standing at this like check out/desk thing waiting to complete the transaction when out of nowhere the baby kicked and I felt this electric shock type feeling run up and down my body. It made my knee jerk and I hit the desk with my knee. I looked like a crazy person and my husband just turned and was like "you alright??" So I told him what happened and he just laughed. Anyone else experience anything like that? That's a brand new sensation for me haha
