As crazy as this question may seem, I really am serious! Can anticipating for your period to start, make it late? I'm not stressing or think I could be pregnant or anything. Just the last time I stayed the weekend with my SO I was on my period (I was hoping for it to start on time and was 3 days late) we are a long distance relationship so this time I really wanted to start my period on time so I would be done by the time this next weekend came for me to stay with him but here I am officially a day late! Has anticipation done this to anyone else??
