I feel your pain hun. Even before I had kids, in my early 20's, I was convinced I was 'grotesquely abnormal' down there. It severely affected my confidence. I begged my GP to send me to a specialist, despite being told by the GP I was perfectly 'normal' and that everyone looks different. I couldn't believe that THAT was normal and insisted I saw a specialist as I felt like a freak.
She agreed and referred me, butnI was given a shameful telling off by the specialist for wasting her time as she abruptly informed me "there is nothing wrong with you, stop being silly!". I went home in tears still convinced she was lying to me.
I started looking into vaginaplasty surgery privately - but felt totally at a loss when I realised I couldn't afford it.
But since meeting my current partner and asking him directly if he thinks I'm "weird down there" he put my mind at rest. I've slowly learned to realise I had spent years comparing myself to women seen in glamour / pornography, but that the vast majority of us general public are actually all different and don't look like these women - especially after childbirth!
After my sons difficult birth (ventouse and episiotomy) mine looks different again. But I have been checked by the nurse and everything is where it should be, I have no health issues to be concerned about, and my OH still finds me attractive - everywhere! In fact, my OH knew I'd get all upset about it after birth so he made me look at it with a mirror together, to show me its not as bad as I think, or as bad as I think he thinks it is!
Im sure this is just the case with you, and that it's just been a bit of a shock to you. I hope your appointment with the GP reassures you and that everything is ok. And if it isn't you're doing the right thing to get it checked out x
