Help!

So I had condom less sex about two weeks ago. I start my placebos tonight ! But I’ve had bad gas since I started this pill. Like I’ll have episodes that’ll last months at a time with like acid reflux and constipation. But anyways. Now I’m having these pangs on both sides of my stomach but when I move it makes a bubbly noise and it’ll travel literally in different parts of my body. My question is do y’all thinks it’s only gas due to my acid reflux and stuff or is possible it’s pregnancy symptoms ? I don’t have any other symptoms just the gas. I take my pill at the exact same time every night. Literally have never gone past the or before the time.
