Going to sexual health clinic 3rd time.

Is it inappropriate? I’ve been to the sexual health clinic two times last year. The first time i went for a blood screening (testing hiv, hepatitis, Syphilis etc) and testing for chlamydia and gonorrhoea vaginally. I wanted to make sure while I was with my husband. So suddenly I got really weird discharge so I went there again although I slept with my husband only. They checked again for chlamydia and gonorrhoea and trichomoniasis.

So I ve had anal sex before I was with my husband. And I want to go again to the clinic to get checked for rectal chlamydia and gonorrhoea but I feel shame to go there a 3rd time... should I go?
