The stalked barnacle Pollicipes pollicipes (Gmelin, 1789), is a strictly littoral and essentially intertidal pedunculate cirripede that lives by forming dense aggregates or clumps on exposed rocky shores and cliffs associated with a high degree of hydrodynamism (Barnes 1996).
Since some women are unsure of the date of their last menstruation (perhaps due to period irregularities), a baby is considered full term if its birth falls between 37 to 42 weeks of its estimated due date. 1  The unborn baby spends around 37 weeks in the uterus (womb), but the average length of pregnancy, or gestation, is calculated as 40 weeks.
36 weeks: Your baby is about the size of a head of romaine lettuce. At the end of this week, your baby will be considered early term.. (Full term is 39 to 40 weeks. Babies born before 37 weeks are preterm, 41 weeks is late term, and those born after 42 are post-term.) Most likely your baby is already head-down. But if not, your doctor or midwife may suggest scheduling an external cephalic version.
