Low supply or cluster feeding

My baby just turn 3 months this week and has been crying for a feed every 1.5-2 hrs, currently ongoing for 3 days already, full latch. I read online that baby goes through a growth spurt at 3 months but however, there is very little info on it. I never had a problem with my milk supply until 3 days ago when this ‘cluster feeding’ happen. Even if i tried using bottle today, my baby also cry for a feed in 2hrs 15mins. First bottle: 100ml. 2nd bottle: 80ml. After this 2nd bottle, i latch her (feed her again) in 2hrs. Any other parents going through cluster feeding now?
