Weird jealousy when I see breast feeding moms

Logically I know I don’t want a baby. I am on birth control and 23 and there’s no way in hell im stopping it. But when I see breast feeding moms which is a lot lately because everyone and their sister just had a baby, I feel this weird tinge of jealousy and do not understand why I feel that way at all and can’t shake it off. It’s like a deep jealousy that I feel in my gut and it almost hurts? It makes me want a baby to breast feed. It’s almost like I feel like it’s not fair, it’s really stupid. Don’t get me wrong at all I’m so happy that everyone had healthy babies and again do not want one right now. And I do not show my jealousy outward because I’m aware that it’s irrational, this is an inner monologue and I just wanna know if that’s normal and how to stop it.

Added: I think I wanna stop it because it’s a beautiful thing to see new mommas happy with their babies but I got this big green monster on my back and it feels ugly and rotten. It’s not inherently a bad thing I guess, it’s probably some weird primal drive kicking in and it’s just confusing. The thought of getting pregnant right now makes me wanna melt into the floor.
