Possible Paraguard Issue?!?

So I had my paraguard placed April 17th AND started a new pack of BC pills that day too (yes I'm staying on the pill too...for many different reasons). I knew there was going to be an adjustment period but I'm getting very annoyed and slightly worried. I have been having a period aprox every 2 wks and its light but lasts 2 wks. Since it was placed my Hubby and I have only been able to enjoy condom free sex 3 times! I've called my Doctor several times they thought it was my current bc pill so they put me on a new one. All was going okay until the other night when the hubs and I were "enjoying" then I started bleeding again. Nothing heavy but I'm so over this! Has any one had similar issues?
