Breastfeeding pain and nipple soreness 6 day of feeding

Does this happen to everyone I posted a pic bc I want to know if anyone else has ever had this happen. It seems my milk hasn’t came in yet and my breast seem like they wanna explode and nipple looks weird to me not sure if she is latching on right bc that’s how it looks after a feed...please comment and advice if you have experience this I’m so worried bc she is losing weight 😩😩 ( top part of nipple just sticking out bottom part more flat. ) that’s how baby latches it seems like she has everything in her mouth
