mamas with big families

For those of you who have 4+ kids, did you plan it that way? Is it hard? Did you consider abortion/adoption at any point? I just found out I'm pregnant with baby number 6 & I'm so nervous & having mixed emotions & I dont have anyone to talk to besides my SO who doesn't really understand, he just supports me with any decision. I love all of my kids but it's obviously stressful at times.
