So on June 4th I got a copper iud a week after my period. I bled for 5 days after that. Instead of my period coming 4 weeks after the original end date, it came 4 weeks after bleeding from the insertion for 5 days. I panicked took pregnancy tests and they came negative. After that period it came 3 weeks after which was a week early but the cramps where bad. Now again it's 9 days before period and I'm camping and bleeding again a little. Should I be worried about this? Has anyone experienced this?
