And she said, "If so, why is this me?"
Rashi says: "If the pain of pregnancy is so great, why did I desire and pray to become pregnant?" And that is not correct.
Rabbi Abraham [Ibn Ezra] says: "She was asking other women if it this had happened to them, and they told her, 'No.' And so she said, 'If that is the regular way,' why do I have such a strange pregnancy." But that explanation would mean the verses themselves are incomplete and lacking information.
The correct interpreation, in my eyes, is that she said, if such a thing is happening to me, why am I in the world? I’d rather die, or never have lived! Much like what Job said: "Would that I had never been!" (Job. 10:19)
