Movement?

So I think I feel the baby move! Obviously not 100% since Ive never had a baby before lol It started this morning at 17 weeks 4 days. To me it feels like very very small bubbles rising to the surface and then disappearing. Like a coke that you just poured in a cup of ice...At first I thought I had fleas on me or something because it was itchy! Which I know sounds gross lol But with 3 cats and 2 dogs it is almost hard to avoid them getting fleas around this time of year. But seriously I was like WTF! and had to lift my shirt to check and make sure I didn't have a little f*cker on me :P So no fleas got me sitting and actually trying to feel what it was. I think it was baby:) Good day.
