How can woman be pregnant?
A woman becomes pregnant when the female sex cell (egg) combines with the male sex cell (sperm) inside of the woman’s uterus and subsequently implants itself on the uterine wall. The sperm can meet the egg as the result of three actions: 1. Heterosexual intercourse (whether forced or consensual.) Heterosexual intercourse is when the man puts his penis inside of the woman’s vagina. 2. In rare cases, if a man ejaculates (i.e. has an orgasm, which releases semen, which is the fluid that contains the sperm, the male sex cells) too closely to the woman’s vagina, the semen can swim up into her vagina and fertilize an egg inside of her uterus, resulting in pregnancy. Again, this is extremely rare. 3. A woman placing donated sperm inside of her vagina. And Kris, a woman only becomes pregnant as the result of either sperm donations, intercourse (whether forced or consensual), (in rare circumstances) fooling around. Everything else that you list can either be listed as subset of the categories I
