Mock embryo transfer

So this is mortifying but I think I may have a tampon stuck in me. I cannot remember if I took it out. I have my mock embryo transfer on Friday. They would be able to see it in there right? If I remember correctly it’s similar to a Pap smear with the speculum. I am just torn if I should try to go to the doctor before Friday to make sure there’s not one in there. I’m just not 100% sure and I tried to find it myself and couldn’t so maybe I did take it out….
