Hi hon,
I agree with Brooke that you should think about this and try and make a decision going with your gut. You definitely shouldn't have the baby if you really aren't ready or able and there's nothing to be ashamed of with that - you sound to have been very conscientious with birth control.
I was the same when I was on the pill I was religious with it and would have been blown away if I had caught pregnant, I wanted to be able to plan for our baby at the right time. Having said that, many people get caught out and when they know there's a baby in their belly something clicks inside them to make them want it and they go on to make brilliant mummies
Only you know what is in your gut. Take your time & think about it for a week or two, you have plenty of time to make this decision xxx
