Your body is probably still adjusting. This doesn't sound like reason to be alarmed yet. Are you trying to conceive right now?
Hi,
I had a mirena out in Jan this year (had it in for a year) taken out to ttc baby no 4. I had a few days of spotting afterwards and then got my period 2 weeks later, I did carry on having periods the whole time the coil was in. I had a coil in before this one and when that was removed I had some minor bleeding too when it was removed. You need to wait for period now, are you ttc? Has taken me 5 months so far and no luck with a pregnancy as yet.
