I have been with my bf for over 3 years and always use a condom. I am also on BC. I usually get my period on tuesday or wednesday and today is sunday and still no period. I have been getting minor cramps like I usually get when I have my period but not bleeding. I miss my period around the same time every year and was told that it was due to seasonal changes. I also just got back to college and have been really stressed. I have not been late or missed any pills but am still kinda worried.
