You know you've gotten them..
I'm so sorry for your losses. Wow, it's amazing what insensitive things people can say to you. I have never had a miscarriage, that I am aware of, so I have never heard these odd "reassurances." I have been lucky that noone has dissuaded me in my journey. My DH is a bit worried but he wants a baby too. My mom is worried but wants a grandchild. They both just want me to be happy. My in-laws and friends say you know if you try too hard it can be more stressful and often times it happens when you aren't even trying. I think they are right about that so to me they aren't being insensitive. I don't stress about it much anymore, I think I did the first two cycles but not since. I'm sort of just having faith, if it happens it happens and, if not, we are lucky enough to have the resources to adopt so that is the plan.
These are the top ones that come to mind...
