Organic milk. A glass of milk. Organic milk refers to a number of milk products from livestock raised according to organic farming methods. In most jurisdictions, use of the term organic or equivalents like bio or eco, on any product is regulated by food authorities.
First Trimester (week 1-week 12) At 4 weeks: Your baby's brain and spinal cord have begun to form. The heart begins to form. Arm and leg buds appear. Your baby is now an embryo and one-fifth of an inch long. At 8 weeks: All major organs and external body structures have begun to form. Your baby's heart beats with a regular rhythm.
Actually the third trimester begins at 28 weeks. It does not really matter what you call it. But I go with 27 weeks because in reality you are pregnant for 3 equal periods of 13 and a 1/3 weeks (or 13 weeks plus 2+ days). That math will give you 40 weeks. So really at 26 and 2/3 weeks (or 26 weeks and 4/5 days) you are 2/3 of the way done.
