Hi everyone, I took plan b (well actually a generic Rite-aid brand) almost 3 months ago and have been nauseous ever since. My boyfriend and i didnt have sex, but i was afraid some of his precum got into my vagina as he put the head of his penis in for about five seconds. I went to the doctor where i didn't tell her i took the pill or had that encounter and she diagnosed me with a yeast infection and acid reflux disease. My boyfriend said he had an STD test and blood work done back in January and hasn't been with anyone ever since. Ive been reading online and they say an imbalance to your hormones can case a yeast overgrowth, which caused all the symptoms im having. Does anyone know if the pill is just affecting me still or if it's something else?
