Hello, I am a 23 yr old female 5'7" 137lbs and have had no serious medical conditions (I'm fairly healthy). Less than a week ago my partner and I were having protected sex and the condom broke. Consequently I did have to take an emergency contraceptive (Next Choice). I have had a yeast infection before and I am having the same symptoms when I was last diagnosed with a yeast infection. Could this be due to the emergency contraceptive?
