Hey ladies, so I'm 13 days late on my period. Ive been with my then boyfriend for almost a year. The last time we did anything was last weekend. Ive been stressing out a lot lately..I recently found out he's been cheating on me throughout our entire relationship!! Me being the forgiving person I am forgave him. That was around the time I was supposed to start my period and it never came. I'm thinking it had something to do with the cheating. I guess he couldn't forgive himself and recently broke up with me, which put me under so much more stress and depression. We never used protection and I'm not on birth control. We use the pull out method and it always worked for us. Ive looked online about this and I'm thinking it's stress but I'm not sure...Help!
