This answer was rated:

My wife has the Mirena coil fitted about 18 mths ago. She recently had a urine test as part of a routine test at her GP and was told a few weeks later it had a higher than normal level of hcg and needed to retest However not long after the original test she had heavy bleed which was not like a normal period. Since then she has done 6 urine tests, two of which have been performand by her GP, and all have come back negative. These 6 tests have all be conducted over a period of 2-3 weeks. Her GP has performed a full blood test for everything include hormones and given her a full internal examination. Her Mirena coil is fine and in place. She has been told she is not pregnant and we have nothing to worry about.
Can someone help she's light on what happened and why she would have a higher than normal hcg but not anymore?
Does your wife have regular periods with the Mirena? If so, had she missed one?Was pregnancy suspected? If not, why was an hcg test done? Thank you.

No she doesn't have regular periods and the urine test was done at the time of her Pap test. There was no suggestion of pregnancy

She used to have heavy periods before Mirena but now these have stopped

Her GP did a full blood test and said she isn't pregnant and hasn't anything to worry about.
A higher level than normal of hcg usually means pregnancy. There aren't many other things that can cause it. Since she had a heavy bleed and then her hcg went back to normal, the most likely explanation is that she had a miscarriage.Pregnancy with a Mirena coil is not common, but it can happen. If a woman does get pregnant with an IUD, miscarriage is likely.
