Is that the baby moving inside me?

Katelyn
I'm not sure if it's the baby moving inside me or not, but I wondered if any of you could confirm. 
I'm laying here on the couch, or I'll be sitting in a chair when I feel this sudden pressure/pain in the lowest part of my abdomen (below where my belly begins and sort of up into it). It kinda lingers for a big, gets a little stronger, and then remains kind of constant. Then, after a while it goes away. 
Is this the baby? I can't help but think that it's the baby turning around and pushing up against me letting me know he/she is there. I'm 14 weeks. Does anyone else experience this? Or can anyone explain what feeling the baby move actually feels like?
I'm so in love ❤️
