Pregnancy with iud inserted ?!? 😳

Ok so I might just be paranoid but is there anyway that could be pregnant with my iud still intact? I've been having regular periods, and I took a PT and it came back negative. Will the iud cause PT to show an inaccurate reading? Also I'm feeling movement in my stomach as if there is a baby moving inside 😳 I've had two kids so I know what it feels like. I keep telling myself it's gas but I'm not sure anymore. Has anyone experienced this? Oh and I have been to the doctor and had a full check up

Update I went to the doctor and they didn't believe anything I said. I know I am not crazy. The lady had an attitude as well about the situation. I knew they were going to do this smh.
