STI help

Sooo I went to the doctor because I was experiencing itching and weird discharge with no odor. While there I decided to get tested although the doctor prescribed me medicine for BV and a yeast infection so I started the medicine and it pretty much helped clear up the symptoms but then I got a call with my results saying that I had chlamydia so I took the single dose that says it gets rid of it in 7 days. I'm on my 7th day and I guess I'm wondering how do I know if the medicine took? I know it's going to bother me until I go back to get checked in 3 months
