There is no set number or time frame as each woman and her partner are different. However the facts are that if you have intercourse everyday or every other day around the time or during ovulation and you are healthy, not on BC, your partner is healthy no drugs, cigarettes etc then you have a high chance of getting pregnant as I believe sperm lives 24-48 hours in the Virginia.
It's not so much having intercourse unprotected that will get you pregnant, you have to be ovulating and that happens one day a month. The egg lives for 24 hours once released.
The average woman will ovulate 14 days backwards from the start of her period. So a woman with a 28 day cycle would tend to ovulate on day 14. The woman with a 32 day cycle would tend to ovulate on day 18. The woman with a 26 day cycle would ovulate on day 12 of the cycle.
There's not really any set number of times - clearly it can only take one time, but then there are many other who try for years before they get pregnant. If you are trying to get pregnant, the best thing to do is start tracking your cycle, so that you can tell when you are more likely to be ovulating - they also make ovulation tests that you can buy at Walmart or CVS.
Like Sephira said, there isn't really a set time until you find out (Which would come in handy if there was!) But I've also been looking for a answer to this very question and so far there's been cases when people find out within a few days or up to 3 weeks. Unfortunately all you can really do is play the waiting game.

There are two parts to your question. if you have sex at exactly the right time and those active little sperms find your egg, 2 days I think. But, it can take 12 months of un protected sex for that to happen. Most people are having sex during their teens and are terrified of getting pregnant. Irony is it takes 12 months on average!
I had two periods last month one on the 1st and the next one on the 24th. I have had unprotected sex since then this month i didnt start on the 1st and i blead on the 7th and 16th both only for a day or two it is almost the 24th and im nervous i wont start could i be pregnant? Also it is weird i had two periods in one month is something wrong?
me and my boyfriend john had sex lasted night and i'm on birthcontroll been on it for two hole months now and he told me lasted night the he cant have kids because he has no sprem but he when inside me for a good amount of time lasted night can i still get pregnant
