Starting to feel weird pains

Am

Could it be the baby? It's literally like a sudden pain but only lasts like 2 seconds? I'm not gassy at all. I'm 16 weeks and a ftm so this is all new to me. Just curious as to if it's the baby or my imagination 😭 I thought I was feeling flutters for awhile but I haven't felt anything in a week but now I'm getting the sudden pains in my stomach. 🤷
