Now you may start to really feel pregnant with a lot of symptoms. Many feel bloated in their stomachs, with a feeling that the period is coming. The breasts feel tender and slightly larger. Nausea may have increased, and many experience vomiting/puking. The sense of smell is enhanced and the taste may have changed.
This week the heart starts to beat, isn't that amazing? At the end of this week, you can probably see a beating heart on the ultrasound. The embryo is around 1-3 mm long from head to tail.
If you got pregnant you already now maybe know it from a positive test. If the test was positive, congratulation! In this week the embryo is one week old, the plum sack and the placenta starts developing. The baby is still a flat plate consisting of two cell layers. One cell is going to become the placenta and the other one is digging further into the uterine lining and becoming your baby.
