The Pregnancy
The duration of pregnancy is 64 to 69 days. The diagnosis can be made either by feeling the abdomen of the queen or by ultrasound. An experienced person will be able to feel the pregnant uterus at about day 16 of pregnancy. At this time the uterus will feel like a string of pearls. After the 20th day of pregnancy one can easily feel the fetuses in a relaxed queen.
