I found out we are related

Good day mamas and papas in the house, please I need advice from you all. I have been dating this lady for 1 year now, we met during our post graduate studies and we fell in love. We have since then been making love and now she is pregnant with my child. The problem I am having now is that she took me to her parents and during interrogation, we found out that we are actually related. We are distance cousins. Her parents don't know yet that she is pregnant and she is saying she wants to take it out. I have been telling her to keep it but she said God is against incest. Please is it okay to kill a baby just because we don't want to commit incest. I am really sad by all this because I love her a lot and even if she allows me, I would definitely marry her after all, it's not new and she is even not that related to me. Please, what should I do?
