Ovulation pain is super-common with the Paraguard (I've had one for 4 years) - but it freaked me out at first too. For the other pain, it could be nothing, it could be a placement issue. I might go back to the OB/GYN to get a placement check - very quick appt. to indicate that it's still in the correct position and that there are no other issues.
I remember that it did take a bit of time to get used to the IUD - just little twinges of "hey, what's that?" Good luck!
