My period is getting late 2 days . i have been doing exercise changed my diet . also i had sex after my last period 19 days later .can i be pregnant?

Am I pregnant???: More likely if you had unprotected intercourse. Timing compatible. If not on BC pills and not pregnant, most women have the onset of menses 14 days after ovulation - but the time from the onset of menses until the next ovulation can vary...and if you had unprotected intercourse around the time of ovulation, well...congratulations!

We don't guess: Are you really asking doctor to just speculate that you could be pregnant. You had sex. Unprotected. Go get a pregnancy test.

Perhaps: Changes in diet and exercise very often alter a woman's menstrual cycle. Athletes very often don't get a period for years during training and competition. If you had unprotected sex about 19 days after your last period, you could have possibly conceived. an ovum can be viable 4-5 days after ovulation. I suggest a pregnancy test.

Take pregnancy test: to know. 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), stress, travel, significant illnesses, oral contraceptives & other meds, Illegal drug use, breast feeding, hormone imbalances and medical problems (i.e., PCOS). Pregnancy is #1 reason.
