Post partum baby kicks?

Maybe this is because I had a tiny human kicking me since 16 weeks but sometimes it feels like I’m being kicked! They’re faint and similar to I’d say gas or a muscle spasm but it’s been freaking me out. I am curious if this is normal, if it’s just my paranoia, or I’m pregnant again and have been blissfully unaware. I do have some tests in a target order but the logical side of me is thinking this has to be a thing I’ve just never heard anyone talk about.
