On the way to work

It feels gloomy today with the grey clouds. On our way to work, my husband saw a faint rainbow in the clouds. When I got into the office, I looked out my window and the same rainbow was right in front of me. It reminded me of a saying about silver lining (don’t quite remember it now). Is this a sign that the end of my infertility will be a rainbow? Well, I can’t see any right now (a sad trombone plays on).
