I have had this happen before. Sometimes during ovulation, you can have this brownish discharge. Count back from the first day of the previous period to the time you had the discharge. Women usually ovulate about two weeks before the next period.
Also the BV may have came back. This is normal because BV is the most common infection . Yeast is second.Cervicitis is also a common ifection. If your cervix is infected then it will cause some bleeding. This can causew pelvic pain but so can ovulation.
However ovulation pain usually occurs on only one side where the ovary is happy go lucky releasing eggs.
I hope that helps but I'm guessing ovulation. If you have concerns , check with your doctor just to be sure.
Hope that helps and if you have questions, ask
