It happens: Some women will opt for BCP's so they can get predictable cycles.From the intervals listed it would be reasonable to wait until 60 days out for a urine pregnancy test if trying. You could wait longer & they are relatively cheep.

3 weeks after sex: 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.
