Right, so you're pregnant and don't know what a woman is.
It is an adult human female. An adult human of the reproductive sex class capable of producing ova.
You might be an infertile woman, or a woman with a variation of sexual development, or a gender non conforming woman. It doesn't matter. You are of the reproductive sex class capable of producing ova. If you have a condition that interferes with your production of ova, you are still a woman: it is a condition that is recognisable only because it occurs in a female body. You are still of the reproductive sex class capable of doing it.
And you can't change it. You can take hormones and have surgery, and you still have a medically altered male or female body.
Less bewildered now?
