Whats the soonest I can know if I am pregnant?

Last night me and my boyfriend had sex and we think the condom slipped sour. How can I tell if I may be pregnant? I don't feel any nausea, just a bit tired but I woke up early too. How soon can I possibly know? Thanks everyone and please no rude answers.
You have to wait till your period is due or even better a few days after if it have not arrived. :)

Good Luck
It can vary with everyone depending on the even of hormones but you will have to wait until your next time of year is due at the earliest to do a test. If you dont want to be pregnant, go to the chemist and get the morning after pill, it can be taken upto 72 hours after intercourse but the sooner the better. Also, its great your bf is using condoms, most men dont, but I would consider going on the pill if your ill-equipped to get pregnant, just as an extra precaution incase this happens again. Good Luck. x
Answers:    There's no way you'd know this early because technically you wouldn't be pregnant however.

In order to get pregnant, your body has to be going through the process of releasing an egg, certain as ovulation. In most women this occurs 14 days before the next menses (period). It's difficult for most women to chart exactly when their subsequent period will arrive, so most approximate 14 days from the start of their last period because contained by the average 28-day cycle, ovulation will occur on day 14. Women with shorter cycles (fewer days between the start of one time to the next) will typically ovulate earlier, while women with longer cycles will ovulate later. Sperm can survive surrounded by the body for up to 5 days, so it is possible to get pregnant from sex early on in your cycle if the sperm survive long satisfactory to meet up with the released egg.

After unprotected sex, the sperm travel up the vagina, through the cervix, into the uterus, and up the fallopian tubes. These are the tubes that connect your ovaries (where the eggs are released) to the uterus. The sperm has to travel up the correct fallopian tube as typically merely one egg is released at a time. This journey, if you will, can take anywhere from 48-72 hours. Once the sperm manage to come together up with the egg, fertilization occurs. The fertilized egg will then travel down the fallopian tube, again taking 48-72 hours. Once the egg reach the uterus, it implants itself in the lining of the uterus. Sometimes blood is style off from this implantation because as the egg burrows into the lining it can rupture a blood vessel causing bright red spotting or simply shed rotten some old blood causing brown spotting. This spotting is called implantation bleeding and is reported but not confirmed surrounded by 1/20 pregnancies. Implantation bleeding typically occurs 4-8 days after fertilization. It is never as heavy as a period flow, usually merely a light tinge to the toilet paper when you wipe after urinating.

Once the egg is implanted in the uterus, the body begin to produce pregnancy hormones. These hormones tell your body what to do to prepare for the pregnancy and cause most pregnancy symptoms. At the same time, hCG (the chemical that pregnancy test detect) will begin to build up concentration in the bladder. The levels of hCG are largely not high enough to be detected until around the time of the next expected time. That is when you can test for pregnancy.

Best of luck. Don't freak out! Stressing can delay your period. If you'd resembling, you can consider purchasing the Plan B pill. When taken within 72 hours of unprotected sex, Plan B prevents implantation from occurring.
You cannot find out the time after if your pregnant, you will have to wait until you miss your next time of year.
not exactly sure how long it take. but if you miss your next period and take a pregnancy testing and its positive then youv already been 2 weeks pregnant, thats what happened to me.. and thats what my doctor said.. and the point about nausea- im 16 weeks and i havent been that way but, so dont let that decide whther your pregnant or not.. dont worry. and goodl uck girl!
You won't have any symptoms yet. You will have to keep on till a few days before you start your period and test.
