5 weeks pregnant using Monistat 7

Amanda • Due Date: January 2, 2017👶🏻
Just wondering if anyone else has the problem I'm having... I thought I had a UTI so I went into urgent care two days ago and i actually have a yeast infection (which I was told is common in pregnancy).  I did my second night treatment last night and started to bleed a pinkish color at 3:00 a.m. I only see the blood when I wipe.  I called the doctor this morning because I freaked out!!! They said I most likely put the applicator too high and hit something or irritated my insides. 
Has this happened to anyone else? Was everything ok with you? Did it happen every time you used the product for the 7 days? 
Any information would help!
