Okay I've been off my birth control for like 4 months at the most. my period has always been around the same time since I started my birth control and when I got off well me and my fiancé did It a day before my fertile cycle did it a day before my peak and I have missed my period but according to the glow it says I was suppose to start my period the 14th... no period and my test said negative. Well I know i usually start around the 16 th in my book still no period and test still says negative any help anyone?!
