Hey ladies, I might have a possible yeast infection.. could a yeast infection interfere with a period? My period was “due” the 18th. But that was 30 days since my last period. My periods usually are 31/32 days apart, so I always up a day. So <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> put I was due yesterday the 19th. -31 day cycle . I didn’t end up getting my period so it upped me another day. Today is the 20th @ 10 and and still no period . (32nd day). Could a yeast infection make a period late ?
