Jeannine, I am also a big advocate of taking anti-D's when they can be helpful.
I should have taken them back when bomb hit and began separation as I was a complete mess, lost a lot of weight, couldn't eat and had more crying jags than I can remember.
Then, went through a scare with a lump found in a mamogram. Like your H, my H was concerned, but separation continued.
I finally got the anti-D's, but now wish I would have done it in my darkest days. It would have helped me keep my head above water on those days I felt like I was "vacating my body".
