Hi if i'm three days late on my period am i pregnant. ....

Check for pregnancy: Check a pregnancy test. Delay for a few days may not necessarily be a pregnancy, but a pregnancy test may resolve that question quickly.

See answer: Though pregnancy always a possibility, especially if you had unprotected intercourse during your "fertile window" (day of ovulation and the 5 preceding days), keep in mind that there are many reasons for a woman to have a delayed onset of one's period: stress, recent illness, change in one's daily routine or sleep pattern, heavy exercise, weight change, travel, etc. Best time for preg. test: 1 wk.
