Would you feel bad...?

Would you feel bad about getting pregnant by someone else? When you were in a relationship for 11 years and never got pregnant but found out your SO has been in a relationship with someone else. And had 3 abortions with that person. So you leave. Then you too link back up only for the person that he cheated on you with for 5 years to tell you that she’s pregnant and she’s keeping it. So you start talking to someone else only to find out that your pregnant 2 months later....and you know it’s not his. Just because you feel it in your heart. But your ex thinks it’s his. But then doesn’t think its his. By the way the person he cheated with had her baby today. I have mine in September.
