Iud mirena 3yrs. Had a period for 4 days last 2 days were brown blood. The next passed a blood clot. Then had light red spotting. Had intercourse my partner said something hurt the head of his penis went to pee and light red blood when I wiped. And answers?

Exam. It is possible that your IUD has shifted but an exam would be necessary in order to know for sure and would be an opportunity to look for other causes if this isn't the reason you are having the bleeding and your partner had pain in his penis with intercourse. Hope this helps.
