Can we check for pregnancy test after 2weeks of intercourse..can we get accurate result after 2weeks..i am eager to check whether i am pregnant r not?

After missed period: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. A negative result on a test done too early is not reliable.
