PLEASE HELP! I need to know if this is normal or if I need to call a doctor!

So, i dont look at my vagina often, but today i decided to check.. i cant see my vaginal hole because that skin at the bottom is covering it. I can feel it when putting my finger under it.. but i just dont know what that large mass is or if its supposed to be there. is this normal?!

are you sexually active?

yes I am. Ive only had one partner since September 2019 when i got my IUD.

was that mass there when your IUD? when was your last pap smear? can you send me a closer picture?
