I think I have Tapeworms?

For the past few days I've been eating a lot of mangoes. I of course washed them but when I was peeling it I accidentally cut off a huge chunk so I just scd it off with my teeth. So in general the outside peel came in contact with my mouth. Is it possible that i got tapeworms? I've had diarrhea, abdominal pains and loss of appetite. Is it because I've just been to much fruit? I'm kinda scared...
