I want a third child so bad.. Its driving me insane.. I love pregnancy, but I dont feel like I can..

I live in a 3 bedroom house.. My son and daughter share a room & we also have room mates who also help with bills and such.

I worry if I do then I wont have room unless we put him/her in our room.. Theb that bring me to the car because it wont fit all 3 car seats in it :( what do I do ? We want to expand we feel so ready. We just dont have the right space right now :(
