I had my period on july 18th and i had intercourse on 24july,26th july and 2nd august, will i get pregnant?is it advisable to take pregnancy test now?

Possible: do a home preg test if negative, you are ok if pos. see your doc for a consult

Possible: It is possible. Might be a bit too early to do a urine test. A blood test might show a positive if you are in a hurry. I would suggest you wait a few days. There are very sensitive urine tests available. Or you could just wait and see if your period comes.

Yes: Do you have regular 28 day cycle? Did you have unprotected sex? Are you on pill? Normal fertility period vries14 +/- 4 ( 10 to 20 th day of cycle). LMP 18th July & timing of intercourse will put you at risk for pregnancy. Urine test become positive as early as 2 to 3 days. Consider doing it on 7 to 10 days after last intercourse. If negative repeat in 3 to 4 weeks. Use first void urine for test

Possible, prob. not: It takes an average of 6 months of trying to get pregnant, so the odds are no more than 1 in 6. If your periods come every 29 days you should have ovulated on 8/2 but intercourse on one occasion when you are fertile does not mean you will get pregnant. Again, it is certainly possible but not probable. It is too early to test. If your next period does not come by 8/18 test then.
