Weird feeling

I dont know how to explain it , i have this weid pain/sensation on my vagina. 
Let me see if i can explain it... You see when you have to pee really bad, &it starts to hurt from taking to long to pee. Thats how it feel plus a tad bit of burning down there. A little tiny but, is more of an uncomfortable feeling. 
I am also waiting on my af , is a little late by a couple days. 
I am also on meds for a bacteria infection. I dont know if its causing this effect. I am just all over the place! 
Helpppp pleaseee , mirroring?
