What Is The Brownish Discharge During Medication For Bacterial Infection?

I have recently been treated for a bacterial infection in my vagina i was given a gel to insert into my vagina every night before bed for 5 nights on the 3rd day i started to bleed and clot. I continued to use the medicine because i thought thats how it cleaned out the infection. now day 7 i have a brownish discharge with tiny particles that are similar to that of a wet scab. My husband and I have been trying to conceive for the past few months could this medication have caused a miscarrage and that is what the bleeding and now discharge is that i'm experiencing?
