A few years ago I wrote a fantasy novel about a pregnant girl. Because souls and death were running themes in that book, I ended up having to tackle the question of if and when fetuses get souls. That felt like a minefield. Also the main character had once had a miscarriage which was very traumatizing to her, and although I am pro-choice I worried the book came off as aggressively pro-life. I kept imagining having to defend myself from readers on both ends of the spectrum. It was a weird experience.
It's interesting you should feel that way, because as a Brit, where we don't have this big in-your-face pro life v pro choice thing that's going on in the USA* - to me, the way you described it I'd interpret it as a character having an internal struggle as she tries to decide what to do for the best. It doesn't come across aggressively anything. It's an incredibly difficult choice to ever have to make and if someone's in that situation, their personal feelings are paramount, wherever those feelings lie on the pro choice v anti-abortion spectrum, and the decision she makes needs to take her own personal feelings into account. If the story shows that internal struggle then that's what the story's about. Pro choice means making a choice - if she's choosing to keep the baby because of her personal feelings towards the unborn child, then she's making a choice. The other side of the debate is forcing women to have babies regardless of their physical or mental health or whether they have the emotional or material means to give the child a half-decent life. That's anti-choice. The "aggressively anti choice" story would be "girl gets pregnant, girl's family force her to have the baby and give it up for adoption because she can't look after it, girl suffers physical and psychological fall it from this, girls own feelings never come into the matter" OR the very unrealistic/propaganda thing of "girl is forced to become a mother, keep the baby, then realises she loves being barefoot and pregnant, marries the boy who made her pregnant before she's too big to look obviously pregnant in her off-white wedding dress, and they live happily ever after while she makes him sammiches, still barefoot in the kitchen."
*there is debate on abortion but it tends to centre around whether the limit for abortions that are not for medical reasons should be 18, 21 or 24 weeks gestation. There are people who think they should be completely illegal, but they're a minority. There are groups that lobby parliament about it, but it's not something that's usually mentioned in election campaigns. It's not the huge political football that it is in the USA.
Regarding the latest question - I've yet to submit anything to an agency so the answer's no
Regarding the question before that - writing prehistoric fiction based on a scientifically accurate interpretation of the fossil record is a bit like conducting a giant thought experiment. Sometimes, writing characters in that situation makes me discover things about the prehistoric ways of life.
Have you ever had a really good story in your mind, then when you come to write it, you totally change your mind and it turns into a completely different story?
