Help idk what’s wrong

I’m freaking out. I remember I had sex a week ago with a condom and it didn’t break. We even made sure by filling it up with water & it had no rips. So Idk if it gave me an allergic reaction since then since it was banana scented. I’m not sure but ever since the inside of my vagina is itchy. Makes me want to scratch it and I’ve also noticed that I’ve been more wet lately. I’m also getting more white discharge on my underwear and idk what’s wrong. I also had sex two days ago with a condom and it didn’t break either. I’m supposed to get my period in 5 days and I’m scared. Idk what’s happening. Any help?
