I have an Mirena IUD for over a year. In july my IUD moved up but the doctor said it was okay. I had unprotected sex on july 30. I didnt get a period thismonth even though i usually get one. the last two months (june and july) i got it twice in a month. i had pink discharge at the beginning of the month. then later in the month i got a sore back and sore nipples/breats. I took a hpt a couple days ago and its negative....

 

What should i do? Im freaking out!
