Yes, that is how I see it too. Her need was to get away from the situation, and this baby was the last thing on her mind, so naturally she will think abortion with the abused state she is in.^^ A woman just came back from a horrible situation and if she were to find out she's pregnant, I'm hella sure plenty of them would immediately think of abortion and not motherly feelings.
Not everyone will be happy to know they are pregnant. A motherly feeling is not always present right after learning of pregnancy. Her first reaction was she didn't want this. That's pretty realistic. She doesn't have to have any motherly feelings.She will now end up getting attached to her child because she's been forced to continue on with the pregnancy. So yeah, she will develop a bond and feelings. But to say that women wouldn't immediately think of abortion but rather only of motherly feelings are putting women in a box.
