Question

I had my IUD taken out feb 5. I bled for 3-4 days a week or so after I had it out and marked it as a period on my calendar well I have been bleeding since March 14. It was heavy and now it's light and sometimes nonexistentant. We had sex yesterday morning and he said the blood was back and it is light again. Plus I have had diarrhea for 3 days is this normal? How can I get it all to stop. We are TTC but, it's hard when I am either always in the bathroom or always bleeding.
