So I have the copper coil and have done for nearly 4 years now. My partner and I never use contraception due to being in a long term relationship. Since having the coil fitted I’ve always been regular with my periods and have apps to track it, however I’m now 4 days late and it’s really strange as I’m never late and if anything always a day earlier than my predicted period and I’m wondering if it could be pregnancy. I know the only way to know for sure is to do a test but what do you all think??
