difference between after getting vs after got

can anybody clarify difference between after getting vs after got…
some times i could hear, some people using after getting for past tense .is this correct?
NB: please correct me grammar mistake from my post if there…it would be great help

Hi,

‘After getting’ needs to be followed by a subject and main verb: After getting the shopping, we went home. Alternatively we could say: After we got (had got) the shopping, we went home.
