So I generally have 3 day, light periods.  Well mine came and went Saturday-Monday.   I am TTC #2 so now that my period is gone, hubby and I are having sex every other day.  We started on Tuesday (day 1 after period) and then again Thursday (day 3, after period, which was last night). Well today I woke up bleeding-- is this spotting or a continuation of my period????  It was heavier than my normal period (which is normally light).  Will this throw off my normal fertility calendar?  I'm wondering if I need to reset the app to reflect today as a period day or if it really just is spitting.  If it helps at all, we had sex twice last night so wondering if that has something to do with it too?
