Fetal awareness and especially fetal pain are controversial, political issues. However, I do not wish to get into politics and want to merely stick to the scientific evidence. I have found statements about fetuses in the womb that seem to contradict each other, yet there has been no reference to the opponents in either side.
Some believe that fetuses do not have awareness in the womb and cannot feel pain. Here is an argument along those lines, claiming that fetuses cannot feel pain, even when their nervous systems and brain are developed, because the chemical environment within the womb suppresses awareness and experience that shapes the brain only happens outside the womb.
However, some other evidence seems to claim that fetuses can have experience. Twins can interact with each other in the womb as early as 14 weeks of gestation, as stated here. It is possible to learn in the womb, and newborns, even after they are born, can retain this knowledge, as stated here.
I'm not sure what to think. Are some of these statements, such as the idea fetuses are not aware, just incorrect? Or can interaction and learning occur without awareness somehow? (I know pain is distinct from awareness, interaction, and learning. What seemed particularly strange was the idea that fetuses have no conscious experience whatsoever, especially as no one making that claim, as far as I know, even mentioned the evidence about interaction and learning at all).
