Been taking minocycline; i'm not on birth control had last period on time & normal after starting medication. spotting this month. is it the meds?

Spotting: Irregular bleeding is one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections ; hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test . Minocycline should not affect the menstrual cycle
