Cat missing- I know this is not pregnancy related

Ashley
Hi everyone, 
My indoor only cat went missing a week ago today and I am absolutely heartbroken. I need some stories of successful cat returns. We have been out calling for him around the clock, including through the woods, posters everywhere, 2 traps set up, garage door left cracked every night, etc etc. 
I'm 6 months pregnant and all of this stress had made me experience some cramping the last few days. I'm just a wreck. Please any advice?
