this is so crazy.. I used tampons. I hate pads. I wear tampons to bed. the second night of my period I thought I put one in after the shower. went to bed and bled through. . went to take my tampon out.... and no tampon. the only thing I can think of is it just fell out cuz it was so full.. and I didn't notice. I was going to check the toilet as it flushes it self cuz the handle u have to pull it up every time u use it. and nobody does!. so then I go to the box of my tampons and count them. I used one to see how big it was to a regular and then the one I thought I used. the box came with 18. there was 16 tampons.. my period is now almost over I used tampons for the rest of my period and I had sex this morning. but I'm starting to feel sick, head ach and stomach. like can a tampon get stuck in you? like in you so far that you can't feel it when you stick your finger in your vigina?
