pregnant on iud?

v

the other day after i finished doing my business on the toilet, two clumps of blood came out. I figured I got my period, but afterwards there was no bleeding and there still hasn’t been. I’m worried I could be pregnant, because me and my bf have been very active recently and he doesn’t pull out. Should I be worried? We’re planning on testing next week to check, but I’m just scared my body is showing symptoms and I’m not noticing.
