I have had my Mirena in for a little over a month. I missed my follow-up appt and have no way to get there right now so I haven't rescheduled yet. Anyway, I have started this HORRIBLE cramping today. I feel it in my butt and legs as well. (Almost like labor pains!) I have had a little look online, and have read that your first period after mirena insertion can be a bit horrific cramp-wise. Is this a possibility? Should I wait it out or start planning a trip to doctors/ER? I know many things can happen. (TMI) OH & I DTD last night, but we do it all the time and I haven't had cramps like this before ... any advice/experience is welcomed. Thanks.
