Broken back - scared of ttc!

Anja
Hey! Last month I fractured my L4 vertebrae. It's still healing but it's been difficult to continue to ttc. 
Just wondering if there is anyone else that has had a bad back and conceived / given birth without complications. 
Trying to bd is hard enough during ovulation. We've been trying for 2 years since a miscarriage. We just seems to have bad time and luck!
