As of yesterday people cannot hear me whether i call them or they call me. The only way they can hear me is if i plug in a set of headphones with the built in mic. Also when there is no mic plugged in and im trying to talk, hello hello hello i can hear myself echo in my own earpiece making me think my mic is fine and its something else.

Ive got tons of performance things installed on my phone and its always worked just fine. Please help me if you can. Thanks in advance.
