Anyone experienced this?

I’ve been given flagly and metronidazole, pills didn’t work at first due to the horrible taste and horrible morning sickness I went thru, and I recently went through a 5 day treatment w metro. gel, I have a small rash going on, and within the days I went through the treatment chucks would come out like that. There’s no foul odor at all. Has anyone gone through this throughout their pregnancy?
