I am on my period right now. I started using a different brand of tampons because I didn't have enough money to get my regular brand. This is the only period which I have thrown up, sweating, cold hands and very nauseated. I went to take out the tampon only to see half of it came out. No the other half didn't come out of the toilet, I have never forgotten to take out a tampon and accidentally put a second one in. Yes I have tried looking (feeling around) but no luck. I can't tell if I'm feeling any differently because I still feel sick and very crampy. What do I do?

You're going to have to see a doctor who will check for pieces and pull them out if any are in there.
