Issues and Concerns post Chlamydia

Hi there,

I am 19 years old and I was diagnosed with chlamydia in June after not knowing I had it for two months. I got it in college after having unprotected sex with a guy. It took me a month to go to my gyno but when I did they did an ultrasound as well as pee tests. I obviously had chlamydia and took the antibiotics for 7 days. they did a Pap smear as well and I got a call that my Pap smear is abnormal. I am worried about what that means in addition to the symptoms I've been having since. I got my period a few days after starting my antibiotics and I continued to bleed for 2 weeks. I got my period again 12 days later and have been bleeding since. I am now on day 12. I am not necessarily bleeding but my discharge in the past 5 days has been brown. I have been on a low dosage birth control for the past year and thought that this would stop this irregular bleeding. I have an appointment this Monday for a colposcopy, which I am nervous about. I just want some answers as to what is going on, and will I be okay? This has caused me some serious anxiety.

In addition to this, I returned home and had sex with a guy who has been a partner of mine. when I found out my diagnosis I told him immediately. he got tested, but asked the doctor for antibiotics before he got his results because we assumed he would have it. he took 5 days of antibiotics but left them at home due to him visiting his parents. he called the doctor a week after returning home because he wanted more antibiotics. when he called them, they told him that he was negative. This means he never had it but still took the antibiotics. Does any of this make sense?
him and I have had unprotected sex since, and I won't have any real answers till Monday. I am just looking for some reassurance on this matter.
