3 month sleep regression?

My son is 12 weeks and this last week his sleep has gone from bad to awful. He was already only sleeping 3-4 hour stretches and then waking every 2 hours but now he will go one 2 hour stretch and then he’s up every 30-60 minutes. On top of this hellish sleep he only naps 30 minutes at a time! Everyone warned me about a 4 month sleep regression but could this be a 3 month sleep regression? I know he’s in a wonder week but damn, this is bad! Trying to find the light at the end of this cranky, sleepless tunnel!
