It takes approximately 36 hours for the sperm to fertilize the egg. That is about 1 day and 1/2. I would say wait at least 1 1/2 or 2 weeks before you take a pregnancy test so the results can come out accurate.

Generally, it takes about 10 to 14 days from the time of conception to accurately detect HCG in the urine. Conception may occur on a certain date however, it can take up to 3 to 4 days for actual implantation to occur. That means that you may have to wait a week to detect hcg at the proper levels.

If you take a pregnancy test a week after conception how accurate will the results be if you take the digital clearblue pregnancy test which is supposed to detect 4 days before missed period?

A week after having sex is too soon to take a test. Although the test says you can use it 4 days before a period is due, it will be more accurate (and cheaper) if you wait until your period is late.
