BV Question also first time posting!!

Lucy
This is my first time posting and this might be a bit of TMI, but my husband and I are beginning to  ttc and this cycle is our first actual cycle trying. I couldn't wait for this period which started August 23rd knowing we would be trying, but right before when I went for a check-up the doctor said I had BV and prescribed metro gel for 5 days, I started it yesterday and tonight will be night 2, so I will be done with the medication about 7 days before my fertile window starts. Im worried this will interfere with this cycle and was wondering if any of you have an opinion or have dealt with this?? Thank you so much for your opinions and looking forward to being part of this community :)
