Prolonged bleeding after mirena insertion


Hello i got the mirena 2 weeks ago. During the first week after insertion, i had no bleeding at all and no cramping. Exactly 7 days after insertion, i started bleeding mildly w/ no cramping. I have now been bleeding this way for 7 days straight.. and no end in sight.

Can anyone help me or give advice? I need to have sex with my partner. It has been a very very long time due to pregnancy/postpartum and this endless bleeding is the last thing I need!
