pelvic pressure

i'm a mom to two wonderful little girls. after having my eldest, i used a combo bc pill. after #2 came along, and it took us so long to conceive with her, we are trying the mirena. i've had it in for one year now....the last few months, i've been having a lot of pelvic pressure and some pain with intercourse. i'm just making sure that whatever dull pain i've been having is normal. it IS about mid-cycle, so i'm thinking i'm ovulating. does this sound right? not sure.....not a mirena expert or anything.
