I had the Mirena removed begining of August, had a normal-ish period starting the next day for five days. Going on my previous spot on 28 day cycle, I was due on last Wednesday. I've got the sore boobs, slight cramping (which is not normal for me, usually have monster cramps) and the general things that could be early pregnancy or pre-period. Have done a test (yesterday) and it's negative. Has anyone else found this with the Mirena? Have googled and lots of women saying same as me, but then no-one comes back to confirm if they ended up being pregnant or not!
