Abnormal vagina 3 year old question

I feel uncomfortable asking about this because it’s so personal, but I feel like I have to. Just to clarify I have already asked the pediatrician office and they said, “”we’ll have to look at her to determine anything”.

So I have noticed my 3.5 year old has an abnormal looking vagina for a 3 year old. I noticed it first when she was constipated one day and was having a hard time pushing. When she was done doing her business I got a whippy to wipe her and when I did (she was laying down because its just easier that way sometimes) I noticed a little piece of tissue protruding from her opening. I was worried that she pushed so hard that it caused some kind of prolapse but those are uncommon in toddlers. She's never tried putting anything in that area and she doesn’t complain about discomfort so I don’t know what it is or how serious it is. At my 1.5 year old’s visit today, I mentioned it to the doctor (well she wasn’t my child's PCP, she was a PA, the doctor was unavailable) and she said they’d have to look at her. But if it’s not serious I don’t want someone else touching my 3 year olds privates. I get that they are doctors and nurses, but I imagine that that would be so uncomfortable for a child especially since we teach her that no one else is to touch there (just mama to help clean her). And since she doesn’t have discomfort she might wonder why someone is looking at something so private when it’s not causing her physical issues. I mean, I don’t even like going to the gyno. Is this normal to have tissue like that? Will she outgrow it? Can anyone share a similar experience? I don’t know what to do. I’m also slightly worried that since the woman I asked wasn’t my child’s PCP that she is thinking negative things about our family or suspecting something terrible. She didn’t accuse or ask accusatory questions but I’d hate for her to get the wrong idea. So I’m only slightly regretting asking her and not her PCP. We have nothing to hide, I just don’t want my 3.5 year old to have an examination if it’s not necessary for her health. I don’t want it to affect her negatively to have someone look at her most private body parts. Thoughts?
