Help!!

Trying to find a manhua where mc likes another guy who's an alpha but mc is a beta and they had sex (i dont remember how) and mc goes to the doctor and finds out he's an omega and he's pregnant and he doesn't tell the alpha. Years later mc is taking his kid to kindergarten or something and he meets the alpha again and mc's kid was friends with the alpha's kid and later finds out it wasn't the alpha's kid the alpha was the kid's uncle and the alpha asks if mc's kid is his kid and mc says yes and alpha said he'll take responsibility and marry him.

That's all I remember. Please help
