Bodys acting funny. Is this normal? Ladies help please.?

Ive been having really bad cramps recently and not feeling too well. I put in a tampon for the first time ever and it felt comfortable, no problem. Unfortunately like a minute later I feel sick to my stomach and lightheaded. I had sudden diarrhea and then starting gagging. I dont know if these are effects from my period because I do get diarrhea usually while on it or if its because of the tampon? It could just be a coincidence that this happened right after the insertion of it.
