Help baby screams when latched?

A • Mama🌈🎀💙

Hi ladies,

My daughter is 3 weeks old and has started to sometimes scream/cry when latched. Not all the time just sometimes. I don’t know why and I can’t figure why it’s just sometimes. I thought maybe it was my supply but she will sometimes unlatch angry like and I’m still flowing and then she will relatch in an aggressive sort of manner (idk how else to explain it). Any ideas? Advice? It’s rather upsetting and I am not sure what’s going on. Thank you for reading and any advice.
