Pregnant

I have the kyleena iud. I’ve had sex without a condom a couple times. He never finishes in me. I’ve been bleeding for a month and a half constantly. I called my gynecologist and they want me to get a sonogram and take a pregnancy test. I took the at home test last week and I was negative. I don’t know if I’m just stressed from nursing and hurrying my grandma two weeks ago. Idk what to do I am at a lost. I’m panicking
