Don't fret over it. Our MDseason lasts until the end of January, and I hunton the QDM land. We take the ovaries out of the does, and measure any fetuses. We have a ruler that allows us to backdate the day of conception. The doe I shot yesterday was bred 10 Nov (single fetus). The doe my friend shot last week was bred 29 Oct (twins). That's 5 less deer that will be around next year...
