If you say the Nicene Creed, Mary is mentioned in that.
Born of the virgin Mary says nothing of her being sinless. And once she had the baby Jesus she was no longer a virgin either.

Depends on how define virginity or loss there-of. Virginity loss generally occurs upon first penetration of a sexual nature. The birth of Christ can’t be said to be of a sexual nature but simply one of birth, and that of Holy Spirit origin. “Joseph knew not Mary until she had brought forth her first born son” Matthew 1;25. Sometime after Jesus was born did Joseph have sex with his wife and thus lost her virginity.
