Do I have a yeast infection?

About a week ago i got itchy and sometimes burny feeling down there. I thought it was due to putting soap inside during my shower. Well, that didn’t cause it. I’m still itchy. It comes and goes throughout the day. I’m feeling it now and I just remembered that in the past like over 7 years ago I had a yeast infection and I needed Monistat. The only reason why I know it was a yeast infection was because I had my mom, but now I don’t have anyone to ask 😔😔 I have no weird discharge this time, that’s why im wondering if I even have a yeast infection as before I remember there to be discharge. I’m so itchy down there and I feel like it’s more in my Lips area and less inside. Should I go get Monistat??
