Family Pressure

My husband and I have been trying for almost five years, and had one pregnancy that made it to 5w3d that ended in a ruptured ectopic and cost my left tube in August of 2015.

Ever since my surgery, many members of my family will consistently ask when we're going to be having a baby. People walk up and touch stomach and ask if it's occupied. A lot of the same things everything everyone else experiences like the, "Don't worry, it'll happen." blah blah blah

I have had multiple talks with everyone that as much as much as we appreciate the attempts at support/encouragement, it can be really discouraging. Is there any other way that someone has found to politely tell people to leave this subject alone? It's been putting alot of pressure on us, and breaks my heart every time I have say that we are not pregnant- yet again.
