Never say never. I know someone who not
only got pregnant
after having her tubes tied, but her husband had had a vasectomy too. That being said, there are other reasons that could be causing your brownish discharge between your periods. Have you talked to your GYN? How long has this been occuring? A brownish discharge, although annoying when it occurs between periods, is usually nothing to be overly concerned about. Accompanied by pain, is a different story. I am not a doctor though.
