TTC no where to do it.

My hubby and I have been TTC for a few months now.  Well his father had a heart attack and we moved across country to take care of him.  We can't get our own space till he starts working. And now my four year old step son is moving in with us and has to share our room.   My father in law is awake all day and night in the rest of the house.  I feel like my sex life and hope of us having our own child are crushed.
