So I went to the bathroom and realized I was bleeding through my tampon. Went to my office and did ten minutes of work before I went to change it. Got to the bathroom and couldn't find the tampon I had in. No string couldn't feel it and inserted finger to find it and nothing. I slowly put in a new tampon hoping I would push against it and know how far up it was but nothing. It went in fine and feels normal. WTH!?!? Is it possible it slid out in the bathroom and I didn't feel it? I have no idea this had never happened before.
