I am on my second pack towards the end. I have taken them around the same time daily, but i am anemic and take iron pills. I usually get a very heavy period, with symptoms dizziness, cramps, bloating, headache. I have protected sex, but my question is: is it possible to get my period a week early, and it being extremely light, almost not even there without symptoms? Or is this not even my period? Last month my period was also shorter than usual, but it was there.
