Hello,
Fertility and ovulation returns soon after getting the coil removed. However it is advisable to wait for one normal menstrual cycle to return before you start trying for conception.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
I think it can vary in how long it takes your body to get back to normal. Were you using Mirena or the copper IUD?
