A member asked:

A month ago implantation bleeding and had a negative pregnancy result. continue to have period. did i test too early? should i do blood test?

A doctor has provided 1 answer

Unclear question: 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. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
