When my first two IUDs were removed, I got a heavy period within 1-2 days of removal. For this last IUD, I had it removed Jan 21 so a little over a month ago. I had 2.5 days of intermittent heavy spotting (never even filled up a tampon) 4 days after removal. Still no period. Took a couple tests with faint positive lines and blood test on Thursday was negative for HCG. I am very confused and discouraged as I still have not started bleeding yet.
