So two weeks ago exactly, I got antibiotics for Chlamydia and I had sex once (with a condom) around a week ago. I had terrible cramps the other day and they made me really anxious. If there's any chance I got it back, would the antibiotics still be in my system enough to cure it again? I heard they stay in for 17 days and it's been 14. I'm not entirely sure how this all works.
