Newborn feedings

My 9 day old newborn is on Enfamil ready made formula, he was 6 ounces above his birth weight at his 1 week check. I’ve been feeding 75 mls (2.5 ounces) for a few days now and I’m just wondering if I might be okay to up it... I don’t want to overfeed but I believe he could eat a little more... is it okay to push 3 ounces this early?

***i see his doctor again on Thursday and plan to speak to her about it then just looking for some insight in the mean time
