I recommend checking out these websites about the Middle Ages and medieval women.
Internet Medieval Sourcebook at Fordham University is a highly recommended scholarly source, including actual texts from the Middle Ages, as well as historical information. http://www.fordham.edu/Halsall/sbook.asp.
Here are some examples:
A basic bibliography of writings by and about women in the Middle Ages.
The actual testimony of the heretic Na Prous Boneta.
A letter to Eleanor of Aquitaine. http://www.fordham.edu/halsall/source/eleanor.asp.
The Canons of the Fourth Lateran Council, 1215. http://www.fordham.edu/halsall/basis/lateran4.asp
Information about films set in the Middle Ages. http://www.fordham.edu/Halsall/medfilms.asp
