announcing pregnancy at wedding

MermaidMama • .24.•.Married.•.5 year old princess.•.02/2018 baby boy.
My fiancé and I thought it would be perfect to announce our pregnancy at our wedding in August. I will be exactly 14 wks +2 the day we make the trip down the aisle. I would like a clever way to slip it in as we do a thank you toast. Any ideas on how to announce without just flat out saying "we're pregnant!"?
