Again, sorry about the traumatic event. I've wondered many times about IVF too. I also wondered what would happen if scientists looked closer as to WHY the miscarriages happened.
A couple of years ago a woman came to me who had 2 miscarriages who wanted help with herbal medicines. I knew she had 2 cats but at the time I didn't know what I know today; she was a little quirky and it makes sense to me, now. To make a long story short she had a boy. Today, with what we're learning now, the most pertinent questions on my lists are do you own cats (T. gondii); do you have "allergies"; have there been problems with mold or exposure to it, etc.?
I think your thoughts to get your health in order is the best thing that you can do!
