I Have A Yeast Infection So I Went To The

I have a yeast infection so I went to the store and bought the monistat treatment. I inserted the pill thing with the applicator and when I pulled the applicator out it had a bit of blood on it. I am not due for my period for about 7 days. I did have intercourse over the weekend so I chalked up to that and went about my day. I just had to use the restroom for the first time and I found pinkish stuff all in my underwear. Also when I wipe it is pink. Should I be worried?
