Chlamydia

I tested positive for chlamydia 2 months ago, the clinic gave my and my boyfriend the medication to get rid of it.

A month later I got tested again and I was told I tested positive again. We waited over 8 days to have sex after taking the medication and we both haven’t had sex with anyone else.

My boyfriend has recently got tested and we haven’t heard back, which usually means he tested negative.

Are there possibilities of false positives for chlamydia or maybe the clinic gave me the wrong results??

(Update: I know you guys think my boyfriend has been cheat on me but I’m 100% sure he hasn’t, also his test came back negative for chlamydia, which is why i think the clinic gave me the wrong results)
