Is abortion an option?

Hi! I know this topic is very sensitive. Please no judging.

I have two boys, a 2.5 year old and a 4 month old. I found out just now that I maybe pregnant with baby #3. Im not yet ready (I know what you’re thinking, I thought of that too). We weren’t careful. I’m thinking of aborting the baby but Im not sure. I dont want to regret this when Im older. Im also a catholic, I dont want tk be in hell when I die. However, having three is just too much. Im going crazy now. I have to decide soon. Please let me know your thoughts. Btw, Im already 36, with stable job but I dont think my company will allow two years of maternity leave. Thanks so much in advance for your answers.
