chlamydia

So i had chlamydia about 4 months ago and i took the 2000mg the four antibotics pill for it but i didnt get retested like they recommend cause im 16 or whateva so i had sex again on new years with my bf and he was a virgin i just want to know if im safe because ive beeen treated and im cure of it and i sure dont want to spread it me and my bf had a talk about it and he says its gonna be ok and that whateva happens that we go thru it together so hes real supportive of me im just be cautious
