So I've never had a yeast infection before and I randomly got one back in march, I didnt know what it was at first and wasn't really sure what to do. I thought i "cured" it but it seems to keep coming back after i shave. After i first realized i got it my "period" was 2 weeks late and lasted 2 days and then next month i was 2 weeks late again and this month i just keep having random spotting. A nurse told me to take a pregnancy test and if its negative i should use monistat. Im kind of nervous because i don't know how to use a vaginal suppository. Can anyone give me advice.
