The Midwife's Apprentice by Karen Cushman

I listened to this book at home. I had downloaded it but the first disc was everywhere. It is only 2 hours and 45 minutes long. I think the original book is a young adult book. It was a Newbery Medal Winner.
The cover says:

Lyrical yet unsentimental, the Midwife's Apprentice won the coveted 1996 Newbery Medal. Filled with striking characters, it paints unforgettable pictures of village life in the Middle Ages, the midwife's craft, and a very remarkable girl's growing independence and pride.
Brat has no name, no home, and no shelter against the 14th-century winter except the foul warmth of a dung heap. So when Jane the Midwife wakes her with a kick and takes the half-starved creature to her cottage, a curious relationship begins.
Jane teaches Brat to gather herbs and make the poultices used to ease the pain of childbirth for the village women. The skinny young girl quickly learns to obey the sharp-tounged midwife, and secretly watches Jane practice her art whenever she can. But Jane is also teaching Brat unspoken lessons that will take longer-maybe a lifetime-to master.

I really enjoyed this book. It has some wonderful lines, the characters are well written, and the story is fascinating. After having your babies you might be interested in how it was done all those years ago. I imagine this could be a very quick read. It would be well worth your time. 

This author has written another book set in these times. The title is something like Catherine Called Birdie. It is about a young girl coming up to the age of marriage. I read it many years ago and like to too.
