yeast infection? **TMI PIC**

So I was itching earlier in January and went to the clinic. My Gonorrhea and Chlamydia results were negative as well as my HIV and Syphilis. The same day I was told that they did see some yeast so they gave me a 7 Day Miconazole treatment. It helped some but I was still itching but less noticeably.  and then I thought I was ok. My period came and no issues. But the itch has come back more noticbly as of last week. And I’m wondering if my discharge resembles yeast infection? I didn’t look at my discharge previously, I just went to the clinic. Currently don’t have insurance so I can’t go to my doctor just yet. But I just got 1 day tricozole and was thinking about trying it tonight. Is it ok to use since I did just do a treatment exactly a month ago? But please, let me know if it seems like yeast discharge or something else? Thank you!
