TPM. Omegaverse. Obi-Wan is an omega. Shmi is an Alpha (AF can gestate and give birth but in her case it was also a bit of omegaverse intersexuality that led to self-fertilization and Anakni).
Obi-Wan is drawn to go with Qui-Gon and Padme for Force reasons. This is mostly out of a metaphysical need to find Anakin.
However.
During the sandstorm, Shmi goes into rut.
Obi-Wan does the math and decides, well, he can open his legs for the mission. He's a bit of a slut anyway, he doesn't mind. Qui-Gon can babysit the kids.
Rut's over in time for saving the rest of the plot. Qui-Gon still dies.
Couple weeks later, Obi-Wan finds out he's pregnant. Is already considering an abortion, but Anakin walks in on him looking at the test and goes "BABY SIBLING???" He was fully aware of and generally trying to ignore what his mom was doing during the sandstorm.
And so Obi-Wan has. Another factor in deciding if he wants to abort or just... give the baby to the creche.
Because he usually doesn't have to worry about the hypothetical baby's older sibling getting excited about it.
