Symptoms to expect

You might have gone through a period of time when you had headaches, due to the hormonal changes, but you’ll feel better now. Blood pressure rises and the uterus increases in size.

This increase presses the veins that carry blood from the legs to the heart, provoking that ankles and knees get swollen. These areas also tend to suffer from fluid retention. In order for blood to flow better you must rest on you left side, never face up.

Another common symptom during this week is to feel stinging or annoyances in the abdomen, due to the stretching that the skin in this area suffers. Use oils and creams to moisturise and protect the zone.
