uti?? or yeast infection

so about a week ago i had a lot of chunky white discharge and i was really itchy, so i went and got pills to treat a yeast infection. i took my last dose on thursday but i noticed today, i’m getting weird pains in my urethra. like they feel uncomfortable but don’t like hurt. i also have pressure on my lower abdomen in my left side. is this possibly just my yeast infection ending? has anyone else has this? please help me out, i’m worried it could be something else.
