had sex around december 28 or 29 took the pill within 48 hours it is now february 1st still havent gotten my period. i been getting tired and lazy and eating a lot more than usual which is weird because its not like me, is there a chance i can be pregnant? im reading that the pill works for some people when they take it within 72 hours and it works just fine for them but idk what wrong with me. also i have an irregular menstrual cycle i always skip a month or two even when i was a virgin so i dont know if i just skipped january and might get it this month but im freaking out
