19 weeks, still haven’t felt baby :/

I see everyone’s pictures on their babybump and mine is SO small compared to everyone’s. I have felt flutters n stuff but I still haven’t felt my baby kick at all. Whenever I feel a big boom in my stomach it’s followed by gas lmfao... TMI sorry 😂 but I literally have SOOO much gas now. I’m farting all the time but I just want to feel the baby. I’m having a boy. Found out at 15 weeks. Everyone tells me I’m caring soooooo small though. I just want to make sure that’s okay cus people on here have big bumps at like 12 weeks. I’m 5’7 200 lbs, I know I don’t look like it but I’m pretty tall lol.
