The uterus is now about the size of a clenched fist. The number of women suffering from morning sickness will increase and symptoms will be strongest at around 10th or 11th week, but most women will be over it by the 15th week or so.
Due to pressure on the bladder caused by the increasing size of the uterus, you will have to go to the bathroom more often. Your breasts and lower abdomen will become taut. Vaginal discharge will also increase. Up until this time, there is a greater risk of miscarriage, so strenuous sports or exercise should be avoided.
The fetus is now 8 cm long and weighs around 20 g. The head, body, arms and legs are beginning to form. Movement will begin after 8 weeks and at around 11 weeks the heartbeat can be heard with a stethoscope.
