Your embryo has completed the most critical portion of development. Their skin is still translucent, but their tiny limbs can bend and fine details like nails are starting to form. Read about your pregnancy at 10 weeks.<\/p>\n
\nYour baby moves through different stages, starting as a blastocyst, then maturing into an embryo, and then a fetus. Around the five week mark, your baby’s heart will begin to beat, at 27 weeks they’ll have regular sleep and wake cycles, and at 39 weeks your baby is physically developed.<\/p>\n
\nThis page is a link to images from a 10 week female fetus approximately 40 mm in size. This stage of development is after the embryonic period (up to week 8), but only 2 weeks into early fetal development. To see other images from this early fetal stage see Category:Week 10 .<\/p>\n","protected":false},"excerpt":{"rendered":"
