A member asked:

Hi, my cycle was very "late" but when it came on it was with heavy cramps and very light. i am assuming it may be implantation bleeding, and was wondering how soon after implantation bleeding can i take a pregnancy test? like how long should i wait?

Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for 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. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
