I glued my ABS pipe with PVC glue... will it be OK

That depends -- You should be all right if you used a blue PVC cement, this is typically 'hot' enough to assure a decent 'solvent-weld'.

OTOH, if you used a clear PVC cement, then you're going to need to cut it all out and start over.

What did the can say on it, if AllPurpose then you're fine.
