HELP. Need advice!

I’m freaking out…so this is a little TMI but I just went to the bathroom and I was wiping and I felt this squishy like ball type thing…when I’m sitting down on the toilet and I lean forward it’s like right on the inside bottom part of my vagina. Its not been there before…it doesn’t hurt at all but when I stand up ever since finding it, it seems like I can feel it. Before I didn’t…idk how long it’s been there but I feel like I would have noticed it before now. Has anyone else had this issue…could my IUD be causing it?? I’m terrified it’s cancer or something…and tomorrow is Thanksgiving and Dr isn’t open…of course this happens at the worst time. Please help ease my mind…:sob::sob:
