Abortion?

So your a Christian... Maybe not one of the type that are completely devout (save yourself for marriage and lead a cookie cutter existence etc) but you don't believe in abortion. You had your first child at 18 when you were assaulted by an abusive ex and kept the child and raised it. And don't regret it even if it was the hardest thing you've ever done. Many years later your engaged to be married and just had a second child to your fiancé. You are all happy. With that being said your pregnancy was particularly difficult this time around. You were placed on bed rest by your OB and while your work was understanding and waiting for you to come back after your maternity leave... You could very possibly lose your job if you were to get pregnant again right away and have yet another difficult pregnancy. Your new child is a month old... You were offered to get your tubes tied during the section but thought it may not be a great idea in case a few years down the road your husband may want another child. You started having sex again before your 6 week post delivery check up. And while you used condoms most of the time... You haven't been started back on your BC and admit a few times you were careless and didn't use protection. While you know this is completely your fault... You suddenly realize through research that you CAN begin to ovulate after having a baby much sooner than what you thought. And while initially you thought chances of you getting pregnant right after having a baby are slim your now finding it's quite the opposite. You don't know if your pregnant right now and your due to have your period in the next week hoping it actually comes. Your due to return to work next month. You and your fiancé can NOT afford to have another child back to back let alone done have the support system with family to manage TWO children that young. It would be impossible to manage with work schedules and for family that help with our work schedules to handle two very young kids. One is enough work etc. your fiancé has made it clear that you guys CANNOT have another baby already after just having one. And your the breadwinner of the family and could lose your job if you'd be placed on bedrest again if you were pregnant again. After one year of being inactive they can terminate you.   So you initially don't believe in abortion .... But are suddenly questioning your beliefs and realizing is easy to feel a certain way until you find yourself in this situation. So do you have an abortion of you ARE pregnant? Or risk a great deal of hard things to happen simply because of your own carelessness and getting pregnant again so quickly after having a baby?
