I have the copper coil, have for 2 years, not had any issues with it still have regular periods and still ovulate half way through the month. This month I ovulated and about a week after had the tinyest little sharp pains that felt almost like implantation pains! (I have children so I know) I’m now 2 days late! I’m never late! Last night I removed my bra and my boobs felt heavy and sore! For 2 nights Iv woke up unexpectedly and not been able to get back to sleep. This is how my last pregnancy started. I’m now a bit worried! But surly it’s all in my head right? I have a coil that’s supposed to be super effective!! Can you even get pregnant on the coil??
