Maybe tmi? Yeast infection

My dr told me to take the 7 day monistat so that’s what I’ve been doing for two days. I’ve never had to use this before this is my first time, I’ve noticed that I had like 3-4 tiny smaller than a pea sized amount of blood when I wiped but once I wipe it’s gone. I don’t have that through the day just when I wake up after using it at night. Should I call my dr or does it seem like the monistat is irritating me? I don’t have contractions or anything weird like that so far. I’ll be 35 weeks Friday. Thanks!
