I got period on 9 aug and finish on 13.i did unprocted sex on 14 can i get preghent on that day?

Not likely: pregnancy happens during ovulation which happens 14 days before the onset of the next period, the first half of the cycle can be any length. If you have 2 1/2 week cycle then yes you can. If you have a 4 or 5 week cycle then no

Extremely unlikely: Technically, a person can ovulate on any day of the menstrual cycle, but it is most common for a woman to ovulate on the 14th day of a 28-day menstrual cycle. If you are 7-10 days late on the next period, take a urine test to check to see if you are truly pregnant.

Unlikely,but possibl: If your menstrual cycle is regular, it is less likely that you can get pregnant one day after menses ends. However, it is not worth taking a chance. I recommend taking emergency contraception, then seeing your clinician about effective methods of contraception. Consistently use condoms until on more effective contraceptive, and always for STI prevention if not in monogamous relationship.

Probably not: It is theoretically possible to get pregnant right after your period, but not likely. You must ovulate to get pregnant, and that generally occurs several days after finishing your period. To be sure you don't get pregnant, always use birth control when having intercourse.

Not likely: If you had a normal period as described it is unlikely that you would get pregnant that day. However, strange things sometimes happen so if you want to be sure not to get pregnant you must use birth control of some kind to prevent pregnancy.
