I ask this question because my gf's mom has always bled even when she was pregnant... Now my gf has really irregular periods, she usually has them at the begining of each month... But she went on the shot (twice now) and both times bleeding just kind of happens through out (usually just spotting for a few days), till the end of the shot then it lasts a week or so.
While on the shot she took some antibiotics and we heard those can actually lessen the shots effect... She also said she had some signs of pregnancy but wasn't sure.
So when would be the best time to get a shot, if ever?
