Yes: Anytime you have unprotected sex you could get pregnant. It can happen on any day of your cycle including during menses, though it is mole likely around ovulation.

Possible: Pregnancy is known to have occurred from sex on any and all days of the cycle. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 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.

Yes: The sperm could survive upto 48 hours
