Where's your egg?: In order to create a baby, there has to be an egg. Where's the egg here? By the time a menstrual period starts, the last egg has already withered away (if there was an egg at all). So, when is the next egg? If the next ovulation is 1-2 weeks away, sperm from Feb. 1 would have withered away by then. That means pregnancy is unlikely, but one can check a home pregnancy test after Feb. 21, if worried.
