Chlamydia ?

Mariah
Sadly im almost positve i have this, the symptoms sent me to the hospital for 2 days and now im on antibiotics for 10 days.. So i know that the symptoms can occur 1 to 3 weeks after contact but i was wondering if they can also appear 4 months after??  Cause i want to know if my bf cheated on me and gave me this. Im just confused haha
