Every month my period changes it’s start time and it’s so irritating and annoying.. I’m not sure if it’s because of age, or stress.. then two days ago I had a oops situation ( unprotected sex) but I’m not in my ovulation/ fertility window.. so I’m sure it was a possibility of implementation but it somehow just stressed me.. am I the only one who gets paranoid when they are late regardless of being sexually active or not?
