My baby is turning 3 months next Sunday...

Maybe I’m exaggerating but I feel so fat I mean I know my body is obviously how it used to be and it may not ever be but I’ve been feeling so self conscious about myself, I don’t have much stretch marks but I do have some and I’m not sure why but it makes me feel so bad about myself... don’t get me wrong I love my baby with all my heart... but I hate my body so much now..
