Doctor?? Vaginal infection? Help😫🤒

So weeks & weeks ago I started noticing a very strong & piercing smell coming from my vaginal discharge before the time of my period. It’s like I would leak suddenly & think that I got my period but it was this clear, watery & strong-odor discharge.

Next I started noticing this discharge at different times in my cycle

Now I usually have this discharge.......💔 & i even noticed that it looks creamy & yellowy

I’ve only been with my boyfriend & I’d like to knock out any suspicion that he’s cheating. Perhaps because we often have car sex where our hands aren’t really clean, we’re sweaty, and after orgasms we put our underwear back on for several hours after that.

I’m 18! I wouldn’t want to have the conversation with my mom about me having sex 😕 are there any over the counter or home remedies??

Before anyone is rude 🙄🤒 please be considerate & don’t comment unnecessarily uncharitably
