chlamydia!?

I'm 32 weeks prego and I've been tested for chlamydia twice & I took meds each time but it makes me throw up! I'm scared to get tested again because I don't want my dr getting mad at me cuz I will be positive again:/ idk what to do! The second time they gave me a black and yellow pill tht I have to take for 10 days two a day but I threw up once
