How much bleeding is too much after a paragard iud insertion? is bloating normal? my body feels like it's trying to push it out. normal?

Depends: Spotting is normal, heavy flow is not, unless you have it inserted in the middle of menstruation, which is recommended, or maybe coincidentally your period started, perhaps a bit early. Check your menstrual calendar. See your doctor for an exam if worried. If you have significant pain and a lot of bleeding, go to ER. It could be perforation.
