Chlamydia

I just found out today me and my partner have chlamydia, one time treatment take 4 pills at one time and that's it how long do you wait until to have sex again? Has any one experienced this

EDIT * For those who are asking how we get it / loyalty. I'm not sure I have thought about it I am pregnant with his child I'm his 4th baby momma (red flags) but anyway I'm not sure I havent cheated in him but as in my last doc visit doctor said I was clean, I found few messages on his phone from ex saying he loved and missed her and how hes lonely and more crap. Know he has pass and I'm no where aloud on his phone etc. So I'm pretty sure he cheated or came in the relationship with it. *for those wondering why I'm still with him is because in pregnant just getting on my feet, no job just got out of jail, my house isnt the best of shape so he can easily take our child away from me if I piss him off right know.* I know its stupid but the only choice right know
