I've been spotting on sprintec for about 3 days now and it happened last month the same. I've been taking it now for about 3 years I don't know if it's normal. and no I'm not on any antibiotics or anything I'm not sure if I should talk to my oncologist . I'm going to see the dr soon because I'm getting off of it because me and my husband are going to try to have a baby. I'm not sure if I should bring it up I want to make sure there's nothing wrong very nervous.
