I had a little bit of a hard time following who slept with who and how it is all connected. Bottom line, chlamydia is never considered cured until you get three negative tests. Sorry about your insurance. Those tests aren't free, someone pays. Whether its you or the insurance company. You CAN, however, try somewhere like planned parenthood which is a clinic or any other clinic you may get a free test or reduced rate test, etc. Look for your options. Chlamydia doesn't have symptoms usually. And you aren't absolutely sure to get it just cause your friend did. So, a lot of unknowns here. Anyway, your post is a bit confusing and I'm not really sure what you are asking but condoms do prevent std's from spreading! And a full std panel all over again would make sense in this situation. good luck
