Typically a dog goes into heat once every six months, and dogs can have silent heats where they don't show outward signs of being in heat, so it's possible Daisy had another heat without you knowing it. She could go into heat any day now depending on the date of her last heat. It's impossible to predict without having had a date from a heat later than May of 2016. You can take Daisy into the vet for a health check to make sure everything is ok with her.
