Why????

So I’ve had my IUD for a year and my periods were normal at first but now they’re coming late and also they last a long time I’ve had my period for 8 days counting today idk what to do 🤦🏻‍♀️

Update: I’m not trying to conceive he does cum in me tho but I don’t want anymore kids I have a almost 2 yr old n I’m done 🥲 Im 20btw but maybe they’re something wrong with me because I do feel tired all the time and sleep a lot.
