Hello, I would be happy to help you with your question.
The potential for pregnancy
with a Mirena
IUD in place is EXTREMELY LOW, but not zero. Given the presence of the IUD and negative tests, I am going to assume that you are probably not pregnant. In any case, you should repeat the test in 1 and 2 weeks just to be sure.
With regard to the symptoms, they might actually be cycle related as the IUD does not prevent your cycles from continuing despite its excellent birth control effect.
