During this week of pregnancy the crown to rump length of the fetus is 0.9 inch to 1.2 inches (22 to 30mm), weight 0.07 ounce (2gm). They are now on the way to forming their testicles or ovaries, getting ready for the next generation. Until the ninth week of fetus development, the fetal reproductive apparatus is the same one for the both sexes. The head is still large and curves into chest.
Each week your uterus grows larger with the baby growing inside it. You may begin to see your waistline growing thicker by this time. A pelvic exam will detect that your uterus has grown from it's normal, size of your fist, to a little bigger than a grapefruit.
Week Eleven: Neurons multiply - Dec 7 - Dec 14
|You are 11 weeks pregnant. (nine weeks after conception)|
The eyelids have fused shut and will not open again until around week 27. The wrists and ankles have formed and the fingers and toes are clearly visible. Genitals have begun to form, but it is too early to tell the sex of the fetus. By this week of the pregnancy the placenta has developed enough to support most of the critical job of producing hormones.
By the 10th week of pregnancy, the crown to rump length of your growing baby is about 1.5 inches (35mm). The baby weighs close to 0.18 ounce (5g) and is the size of a small plum.
