This is my first month off birth control after about two years so I don't really know when I am supposed to get my period. It always came on the same day when I was on bc but now I just have no clue! I am dying to take a test but I don't to do it too soon! My last period started on July 18th (today is August 17th) and ended on on July 21st? Is it too soon or have I probably already missed my period and not realized?
