I didn't plan this...

I'm devastated, shaken to my core. I always wanted another baby to call mine, just not yet. I'm the mother of a 3 yo and a 1 yo, we live in a 3 bedroom single wide that I love because we bought it and it's ours, we don't owe anyone anything. But here we are and I'm pregnant again, we've been so careful using fertility awareness and abstaining from sex a few days before, after, and for the duration of ovulation. I don't know where I'm going to put this new baby, how will I love this new baby, and how am I going to nurse this new baby with two others also nursing, how do I do this? I've cried so much already today and I feel so broken, and I'm angry with myself for feeling this way when I know there are women who would give up everything to be me... I know that God has a plan, I'm just having a tough time seeing it.
