Yeast infection???

Uh soo this weekend i spent the night at a friends house and we had protected sex throughout the whole weekend, flashforward to monday and my vagina smells weird even though i take showers everyday and even after we had sex. When i wiped down there with my towel i saw a small little clump of white on it (it wasnt alot) and today i had discharge on my underwear after i took a long shower and the white little clump again. Could i have a yeast infection??? If so any tips to get rid of it?😭😭😭😫😫.

(And i cant go to the doctor cause my mom doesnt know soo im screwed🤷🏽‍♀️)
