(2019). The gestation period for the mouse ranges from 18 to 22 days. (2007). Clin. Spiral arteries then converge at the trophoblast giant cell layer and empty into straight trophoblast-lined "canals". If she isn't, then I would wait a week. A few hours after conception the zygote starts traveling towards the uterus where it will start to divide and grow. Pregnancy is divided into three distinct stages: the first trimester, second trimester, and third trimester. Baby House Mice. Histology atlas of the developing mouse heart with emphasis on E11.5 to E18.5. However, in the case of human, direct canalization of the urethral plate occurs in the glans, while fusion events are involved in formation of the urethra within the penile shaft, a pattern exactly opposite to that of the mouse. Herculano-Houzel S, Mota B & Lent R. (2006). The table below gives an approximate comparison of human, mouse and rat embryos based upon Carnegie staging. They are bright pink and you can see they will have black eyes. (1962) Altman PL. Exp. (1989). 1 Day. Takaoka K & Hamada H. (2012).
