Question about breastfeeding

So I think I messed up my milk supply idk I'm worried about anyways. This weekend I was pretty busy and away from Leland so I pump for the weekend well I didn't think he would be asleep when I seen him and I didn't have time to pump while he was asleep or even home to pump. Saturday it was 8 or more hours since feeding him and today 4 or 5 hrs in between.. I feed him one side and just pump the other side I only got 1oz I was getting 2 or more pre boob I tried to pump the side I fed him on nothing. Is there away to get it back? Or am I stressing on it to much. I'm just worried I messed things up 😔😭 and I've been pretty emotional today between school going back and work coming up soon would that have something to do with it? I just want to make this work for him 😔
