The child
The embryonic stage is over, and from now on the embryo is known as a fetus (we’ll refer to it as “the baby”). Your baby now measures almost 1 inch (2,5 cm) from crown to rump, and the neurons are now developing exponentially. The baby’s ankles and wrists have formed, and fingers and toes are visible. The buds of twenty tiny teeth are forming in the gums.
The sac in which the baby is now located contains about 100 ml of amniotic fluid that allows your baby to move around and exercise its arms and legs. This fluid also provides insulation to help the baby to maintain an even temperature and cushioning to protect baby against bumps and blows. It also provides the baby with nourishment.
Amniotic fluid is produced in the fetal membranes and the entire volume of amniotic fluid is renewed over 24 hours. There is normally up to four cups (one liter) of amniotic fluid present by the end of the pregnancy.

Mother
You may easily get upset or irritated about things that normally wouldn’t bother you. Blame it on your pregnancy hormones. Natural anxiety about the pregnancy and motherhood can also trigger mood swings. It’s common to be exhausted in the evenings and to want to call it an early night.
Your breasts may be larger, so that you need a larger bra. A firm bra that provides plenty of support is a comfortable alternative. Breasts are often at their most tender during the first half of the pregnancy.
If you’re not taking vitamin and mineral supplements already, now is a good time to start. You could add an iron supplement as well.
Remember to include your partner and any children you already have in the changes you’re experiencing. Most likely, they want to be a part of your pregnancy and the more you include them, the easier it will be for them to support you.

Partner
Your baby has now passed the first of the most sensitive developmental stages, and everything will continue to develop from now on.
Do you feel the time has passed quickly or slowly so far? Parents-to-be often find that their perception of time passing varies. With all the physical changes happening to her body, the mother-to-be might feel that the first few weeks go quickly, while her partner may find the time drags on. As the pregnancy progresses, you’ll probably find that the weeks go more quickly and that it becomes a richer experience for you.
