Period was 11days late(just started tonight) had a few pregnancy symptoms tho. could i still be pregnant? what would cause it to be late with cramps

If it is your actual: Period then you aren't pregnant. If uncertain then take a pregnancy test. Reasons for missed / late period include: an anovulatory cycle in which no egg is released, marked v or ^ in weight; eating disorder; over-exercising (endurance athletics), travel, significant illnesses, oral contraceptives ; other meds, illegal drug use, breast feeding, hormone imbalances and medical problems (i.e., pcos).
