"Waiting for science babies"
Hmm... I don't know if that's necessary when you have magic like in this Pretty Cure fanfic: https://www.fanfiction.net/s/7871631/1/Left-Behind https://www.fanfiction.net/s/8024815/1/Second-Chances
The important part: https://www.fanfiction.net/s/8024815/8/Second-Chances
Summary is that Honoka Yukishiro was raped by "Mori-san" (a man named Osamu Mori) and she thought the rapist was the father of her child (Akiko Yukishiro) but it was actually her long-lost, presumably dead BFF-turned-lover Nagisa Misumi. The sperm that impregnated Honoka when she got raped was taken over by the feelings that mixed in her body, as she subconsciously cried out for Nagisa, who then had the overwhelming instinct to protect her. The feelings met in Honoka's body because Honoka was that severely weakened, and they mixed. Nagisa's feelings took over the sperm in Honoka's body (as it was a foreign substance) when under normal circumstances it would help Honoka heal faster. And when I say "take over the sperm," I mean her DNA wound up in the child Honoka conceived that night. And voila, two women have a biological daughter together. It's really beautiful in my honest, not-so-humble opinion.
