TMI * yeast infections

This entire pregnancy I have been dealing with yeast infections every single month almost like its replacing my monthly cycle . This past month and a half I cant seem to shake this damn yeast infection . Ive done antibiotics, ive done 3 different creams ( 2- monestat 7 day , and a 3 day prescribed ) AND IT STILL HASNT GONE AWAY . Wtf am I doing wrong. I feel completely embarrassed and disgusted . Has anyone had this happen to them ?
