I've taken Ortho Tri-Cyclen for years with no issues, after I had my son they put me on the Ortho Tri-Cyclen Lo. It's suppose to have low hormone levels in it, have you tried it? Not sure what Paragard IUD is though. I hope it works out for you though hun, maybe you should stop taking whatever pill you are taking now, let it get out of your system and contact your doctor and see what they say?
