Yeast infection HELP

So I went to the GYNO last week for a regular check up and found out I had a Yeast Infection. I was written a script for an oral medication but with thanksgiving and the pharmacy being busy it wasn’t ready for almost 4 days from when I initially needed it. I was uncomfortable so I ended up just getting monostat 1 and used that instead. Obviously it’s been coming out (tmi) but it’s been 4 days and today I am having the worst odor imaginable. Is it just from the monostat or is there something else going on? Should I take the prescription now even though I took monostat? I am a really clean person and never have issues but I think the initial yeast infection was due to wearing tight clothes & being on my period. I just don’t know what to do!
