Won't Stop Crying 😭

My son is just over 2 weeks old and all day he has been crying almost non stop. He feeds just fine (he's been getting both breast and formula because I'm not producing enough anymore), he's been farting/burping like normal and sleeps okay but as soon as he wakes he's almost screaming. For the last two hours all he has been doing is crying off and on. He's full for sure, cause he won't take a bottle or the breast, we've changed his diaper a few times, and passed gas like normal. We thought at first he was constipated cause he hasn't pooped since yesterday afternoon, but he hasn't really shown any signs of it except the crying. When he cries it turns into a whimper/screaming cry and lasts for a few minutes then he stops. Idk what to do anymore, he won't stop and both my SO and I are getting frustrated 😞 We've tried playing music softly, gripe water, swaddling, skin-to-skin and nothing has helped! I feel so helpless and I want to cry along with him because he's so upset and nothing I do works 😭 What could be causing his crying, what can we do to stop it??
