Jump in and get that pollen onto the mother flower. In rainy climates sometimes Mother Nature needs some help getting squash to form and as long as the female flower is developed enough to open the petals, it is mature enough to accept the pollen. Another trick is to plant flowers such as sedum 'Autumn Joy' or sage near your squash so that the bees will be drawn to the area and help out with the pollinating.
