Why won't my iphone 5 charger fit in its slot all the sudden?

My phone fell in the toilet so i put it in rice… And then it was fine so then i put my charger in and it wouldn't fit… So i took tweezers and got the the rice that was stuck out and i put my charger in and it finally fit but it will not charge what should i do? My phone is working fine now but it just won't charge.

Take it to the apple store. I think water may have gotten into your phone. That's probably why it's not charging
