Second trimester

There are a couple of methods to divide the 40 weeks of pregnancy into trimesters. One is by development, by which the 2nd trimester starts at 12 weeks. This takes into account the development of the baby, and at 12 weeks all major organs are developed. The other one is by gestation, by which 2nd trimester starts at 13 weeks 3 days. That's what you get if you divide 40 weeks by 3 (for trimesters).

In any case, today we're officially in second trimester!!

I forgot to post this on Wednesday, but better late than never! Lovebug is this big:

Your fetus is forming teeth and vocal cords... savor this, their non-functional phase. Baby is approaching normal proportions, with a head now only one third the size of the body. Intestines are in the process of moving from the umbilical cord to baby's tummy. (Much more convenient.)
