Could it be a sign?

I've been ttc for a while with no luck because I haven't been ovulating. I took letrozole along with metformin and I feel pretty confident that I will O this cycle. I was sitting on my porch yesterday cd 11 and a grey butterfly landed on my finger and flew away after about 3 seconds. Today I'm sitting on my back porch and a beautiful yellow butterfly flew around me about 5 or 6 times before flying away. Could this be a sign?
