Hi Savannah,
I am so sorry to read about your losses. I had four miscarriages. The two embryos that were tested had chromosomal defects, so quite likely all due to "stale eggs".
After three years of trying and five unsuccessful (and expensive!) IVFs I had given up on my own eggs and was ready to try with donor eggs. That is when I fell pregnant naturally (by accident!). I gave birth to my gorgeous son at 44.
Don't give up. It only takes one good egg. Literally. Keep trying; every month could be the right one.
Wishing you all the best.
