After wiping, there was a pink stain on the tissue

I’m sorry to bring up a slightly private matter. I asked the pharmacist about itching and discharge, and without seeing a doctor, they gave me suppositories, which I used last night. This morning, I saw a very light pink stain on the tissue in the toilet, and it feels like there’s burning inside; I feel it more. My period is still a while away, and since there hasn’t been any intercourse, I’m confused. Should I wait and see if this medication causes these symptoms on the first day, or do I need to go to the gynecologist? I’m not sure if it’s something urgent.
