Is Bleeding Due To Boric Acid Irritation And Intercourse?

I used boric acid pills for 5 days in a row M-F bc Ive been having yeast infection problems and wanted to make sure it didnt come back. I have been off it for the last day and a half but was going to start back up to 3 times a week as the doctor prescribed. I had sex the thursday and friday before putting boric acid in because I thought I didnt have an infection. I noticed a little bleeding yesterday and today. That is from the irritation of boric acid and sex I assume?
