Don’t rely on a home testing kit. Your health is way too important to monkey around with. Go to a local hospital and get a full batter of tests for all sexually transmitted diseases. Have your fiance do the same. You didn’t mention if your fiance slept with men recently, while you were dating, or in his distant past. If it’s while you were dating and a couple, and he had unprotected sex, you have a serious, complicated problem because not only did he cheat on you, but he put your health at risk, as well as his own.
I hope that you and your fiance are both healthy and that you see a doctor soon.
