I am taking doxycycline and had a cervical biopsy almost two weeks ago. is it normal to still have brown discharge and can the doxycycline contribute?

Two weeks ....: ... is near the outside time limit for seeing bloody discharge after a cervical procedure such as a biopsy. But it would be safe to watch it ... it should taper off completely within the next week or so. If not, you should contact your doctor. I doubt the doxycycline has anything to do with it. Good wishes:)

This is okay: Especially if the biopsy was large, it may be a few more weeks until things get back to normal. The doxycycline probably isn't a factor.
