Thanks for your consult at DoctorSpring.com.
The possibility of being pregnant while on the Mirena IUD and after having had a proper normal period , is very remote, almost next to nil.
However, only rarely, in some circumstances, bleeding might go on with an ongoing pregnancy, and of course, the IUD has a negligible failure rate, but it is there.
So the possibility cannot be excluded.
Pregnancy can be easily excluded with a simple home pregnancy test. Once that is negative, then you can be assured on that count.
If pregnancy is ruled out, then the painful breasts could be due to fibrocystic breast disease. This is a condition where the normal lumpiness and density of the breasts is increased, above what is average.
It is NOT cancer, and just leads to increased breast tenderness and slight discharge at times.
It is caused by hormonal imbalances. Please consult a gynecologist for simple clinical examination and if necessary , imaging in the form of a sono mammogram, to exclude this breast condition.
It is easily treated with vitamin E, evening primrose oil, calcium and sometimes pain relievers.
So do not worry.
Take care, and please feel free to ask for further clarifications.
Patient replied :
Thank you very much I took the pregnancy test hours after sending in this question and it was negative. The day after the pain slowly went away and now I am back on my period. Should I expect to have these symptoms on a regular basis? I find it very strange in this instant because this has never happened to me before.
Hello, good for you, that you are on your period now.
What this boils down to is - the breast pain and tenderness was part of your pre menstrual syndrome.
On Mirena, lots of women have this side effect of breast pain and tenderness.
This was the first time you experienced this, so there is no reason to think that this would be the norm henceforth.
