Got paragard iud monday (had mirena in past). should i still be bleeding (wednesday)? should i go back to pcp?

Probably normal: Placement of an IUD sometimes involves dilating the cervix which can result in some bleeding. The IUD is placed through the cervix into the uterine cavity so even if dilation is not necessary, bleeding may still occur. The Paragard IUD lasts up to 12 years and contains copper and plastic. Bleeding for a few days after IUD placement can be normal unless it is heavy and painful. Then see PCP.
