Pregnancy with the Mirena

Valentina
I haven't gotten my period in over a month, the last time I bled wasn't even really a period, it was just light spitting for three weeks and since then nothing, but I'm getting a lot of the pregnancy symptoms like I did with my daughter, insomnia, sore breasts, dizziness, extreme hunger, and my pelvic area has been growing steadily, I went to the doctor two weeks ago and they took a regular P test but said it was negative, but I've heard women can get pregnant with the mirena in, does anybody have any helpful insight on what to do? If so I would appreciate the help, thank you ladies
