Advice for a panicky mom

I'm panicky and overthink but I honestly believe I'm not producing enough milk. My ds is 6 weeks old and cluster feeding but was still acting hungry after I fed him so I started pumping while feeding I wasn't concerned at first with only getting an ounce as he'd just ate but I caved and gave him a bottle the next feeding he ate a full four ounces happily but I pumped right after and only got an ounce again this time from both sides together.

How can I boost it quickly

Is this normal if he's eating every hour

What can I do to help keep him full until I've produced enough??
