TMI! Freaking out

Ok so I am 6 weeks pregnant with baby #2 and I was in the shower and when I went to wash my lady parts, I felt a huge bulge inside my vagina and what feels like a hole or an opening on the bulge. Wtf is it?! I've googled for the last hour to no avail. It's the size of a small egg and again, there's like a crater or hole or something and I've never felt it before. Was not like this a couple weeks ago! Is my cervix pressed way down or is it a freaking tumor or cyst or something?!
