Was Mary Magdalene chosen to be the first witness to the resurrection because the testimony of women is more credible than that of men?

I was listening to a preacher and he made this claim that a woman was the first witness to the risen Christ because traditionally our societies hold the testimony of women to be more credible than that of men. I thought Mary became the first witness because of co-incidence but he suggests otherwise, is he correct that Mary Magdalene being the first witness to the risen Christ was part of God's plan because the testimony of women is more credible?
