possible miscarriage..?

my periods are pretty regular & on time. i use P.C. to track my periods & it’s normally accurate each time. i’ve been on birth control since my sophomore year of high school (i’m a senior in college now) & have never had a pregnancy scare. i mean if been a couple days late but i believe simply from stress..

there have also been times i spot randomly before my period, even if im not supposed to start soon, but it’ll be very very light… i am like full on spotting like im about to start my period TODAY.

i had my last the 31st-5th of feb & am not supposed to have my next until march 2nd… help?!
