FTM, trying to survive another night..HELP!

My baby is 2.5 weeks old. Today is his actual due date. I had him at 37.5 weeks. The first week, he got to where he would be wide awake and fussy after the middle of the night feeding. Going into week 2 and for the last 5-6 nights, it’s changed to him crying after his 9:00 feeding. Within 30 min of me putting him down, he’s crying. I soothe him, within 15-30 min he’s crying again. This process continues until time for our middle of the night feeding around 12:30. In the beginning few nights, he was fine once we made it to that feeding and he was put down. Last night, this process lasted until our 4am feeding. I am exclusively breastfeeding. He is super happy all day and hardly cries. The last 2 nights, he has spit up after his 6:00pm feeding but no other times. Could this potentially be colic since it’s the same pattern every day? Any tips?? I’m struggling with the lack of sleep!
