I don't understand how he(old troll) was misleading people??!? you asked a question, he responded, and 10-1 that's going to be the most popular answer in this thread.....in fact that would've been my suggestion as well. a gyno is specially trained in this department, they may know to look for certain things that a gp may not.
i would look to a gyno, specifially. not the family practitioner who can do the pap and lal that, i mean a gyno. they have more specific information about these things.
What kind of IUD is it? It seems odd that it would only happen during your period. But I definitely think you should see your GYN.
i would definately go to a GYN,. i think thats the advice your going to get even following my reply. it could have something to do with your IUD. or an infection, a form of hpv, cancer, who knows? a gyn would.
