Yeast infection 11+5

Talked to a nurse today without an appt at my OBGYN and she said to get Monistat and try that.. if it didn’t clear up after the 7 days then to call and they’d call something in for me. But the only thing that’s 7 days is the applicator monistat. This may be a dumb question but is it safe to inject the cream into my vagina while being 12 weeks? This is clearly my first child. I just want to be as safe as i can. If anyone has any advice, please lmk!
