Weird thing in vagina ??

So. I’m 34 weeks pregnant and I have a history of preterm births (this is my 5th baby) I was also told I have HPV when I got my pap this year. I was feeling lots of pressure and you know.. decided to look down there with a mirror since I was told baby is head down and I’m 3cm dilated.

I noticed in the opening of my vagina right below my clit there was some bulging looks kind of like a brain and when I pushed (like to poop kind of) it would bulge out more..

Question : is this normal??

Is it because I’ve had 5 kids?

Is it because I have HPV and could be warts?

I’m really confused and idk if it’s normal or no
