Variable: Under the best circumstances a woman about one in 3 chances of conceiving. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 2-3 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. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.

"Out and in": Sperm ejaculated outside of a warm moist vaginal environment can't swim and don't survive very long. Manually placing the ejaculate in the vagina, may or may not work.
