Okay I'm on BC have been sinceAugust and last month my period was about 5 days long. Pretty normal flow. This month I was a few days late and it only lasted 2 days(probably filled 2 whole regular tampons) me & my bf don't use condoms cause I'm on the pill but now I'm feeling nauseous, frequent headaches, & I pee all the time. I also have strange cravings I'm a vegetarian but was craving chicken & cherry sour candies so bad. I took a test before my "period" cause I was late and it was negative. Should I retest now? Or am I just freakingout  out?
