After getting anxious cos my period was late (with a BFN) and worrying my mirena stuffed up my fertility, my period ended up being only 2 days late! I saw my OB/GYN today who had pathology results from when my mirena was removed and my uterus and endometrium are fine! He reckons I'll get pregnant real quick! I only had my mirena out 7 weeks ago and my cycles returned to normal right away so that's awesome... And I totally worried over nothing!
