I started using Lutera last month and on the 20th pill/day I started having spotting, feeling "heavy" stomach (just like I normally do before periods), etc. though I was still supposed to be on hormonal pills, not on the last non-hormonal row. So now it's my third day of the last row, spotting continuous, but I still don't get periods. What if it won't start at all? Just finish the current pack and switch to the new one? Thanks!
