Hi I have the copper IUD I have two babies. They are 12 months and a day apart. I have had unprotected sex and missed my period. Also the last period I had it ended then started again about 5 days later. Now that I missed my period its been about a week and I have been spotting brown here and there these past few days. I had dark blood when I wiped one time so I figured I might start my period but when I went to wipe the next time nothing was there and after that it was brown again. What are your thoughts?
