Vagina just isn't right... 8 months PP 😥

So after my son was born (very traumatic birth) I sort of noticed things were very loose down there. I didn't stress too much bc I know it can take a while to heal... but now 8 months later not much has changed. I'm suffering from constant 'vaginal air' getting trapped and making noises whenever I sit, stand, bend, during sex etc. Things just never tightened back up. I'm really embarrassed to talk to my doctor about it...has anyone else gone through this???
