no I don`t think your pregnant!
How long have you been using the mirena
If it`s just been inserted - lots f women suffer from breast pain
in the first few weeks. But maybe the mirena has been in for longer.
Anyway if a woman gets pregnant you should see a positive urine test 2 weeks after conceiving.
You have done NINE tests - there is no way that can be a mistake, if you followed the instructions.
You also took the morning after pill - although if you have a mirena you don`t need to.
If the mirena has been isnerted properly - you have one of the most reliable anticontraceptive mehtods available! And you have a double back up with the morning after pill.
You might have an ovarian cyst
that is causing the problems.
Your blood test
will come out negative , too, I´m sure.
Don`t be worried, relax, go to the doc`s tomorrow and ask for an appointment to check out the other symptoms.
