hi, i had a question about my period..i had my last period on febuary 3 and it ended on febuary 8, and i was expecting my period on febuary 28 but it didnt happen i didnt get it, then on march 3rd i got a spotting bleeding it was like mucus clear but with little blood and then it just lasted 1 day..and i have had alot of stress also, so i dont know if i had my period that day or if my period is late and i could be pregnant??? also i checked online calculators were you can find implantation bleeding day and my result was that i would get implantation bleeding on the febuary 26, but it didnt happen, im so confused
