Growth spurt question?

My son turned 5 weeks this past Friday. I noticed yesterday and already today he does not want to leave my side. If I put him down he only stays down for 20 min most. I know he is going through a growth spurt so I'm fine w it but what concerns me is he has only been pooping once a day if we are lucky but he pees so much! He has also been cluster feeding since yesterday and went from 3 oz to 4 oz or a little more and he wants to eat almost every hour or hour and a half. Is it ok to feed him that much milk that often when he isn't regular with his bowels? He is strictly formula fed too. He also slept in the bed with me for the very first time (and hopefully last) but it was the best sleep we've both have gotten lol any advice is appreciated ladies😁
