not sure if this is the right one but similar https://www.mangago.me/read-manga/fatal_oxygen/
Unfortunately it's not the right one, thank you regardless though!

Looking for an omegaverse where the alpha kinda abandoned? (Might have kicked him out) when the omega told him he was pregnant because the alpha thought that the omega cheated on him (he didn't though). The omega has the baby and runs into the alpha again (several years later) and the alpha tries to get back with the omega and eventually succeeds. The kid is the one who runs into the alpha first if I recall, the kid kinda just went into a back alley I think and the alpha was having a hard time or smth.
Sorry I'm not sure if this is enough detail or not, and I'm not sure if this description makes sense.
Have a nice day everyone! (づ｡◕‿‿◕｡)づ
