1 month from period: I would wait about 4 weeks from your last period. That is a reasonable time to check. Also you can be pregnant with a very early pregnancy and the pregnancy hormone will be lower. When the hormone is low it may not be detected on a urine test. So waiting 4 weeks is the best time.

See below: 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
