territorial over new baby

Any other FTM or Mom's in general that are pregnant and feel like their baby is just there's? I know it sounds silly and a little harsh like I know he's my boyfriend's baby too and part of my family as well but I feel like he is all mine and I want to keep him to myself. Ive been carrying this child for so long and he's been apart of me for so long I almost feel like I don't want to share. I guess it's my hormones and motherly instincts trying to be protective. 😂😂
