Please help!!!

Okay sooooo I’ve always been told to be aware of what the inside of your vag looks like just Incase something starts looking different lol so sometimes I’ll take pics and look (probs tmi) but my question is, is there supposed to be alittle white on the inside of the vag? Like when I take pics of it I see a cloudish color on the side but it’s very small.... is that normal?? I’ve seen it there before this too but I just need someone to inform me!!!!!
