You at 8 weeks pregnant
Physical symptoms at 8 weeks of pregnancy
Your uterus is about the size of a tennis ball. It’s putting pressure on your bladder, so you might be feeling the need to go to the toilet more often.
Your body is making a lot of hormones to help your baby grow. Nausea peaks around this time, so you might feel quite sick.
Emotional signs at 8 weeks of pregnancy
You might also feel more emotional, and you could be happy or grumpy at a moment’s notice. Or you might feel like you have a lot of energy.
Either way, emotional swings are normal when you’re pregnant.
If you’re not sure when you became pregnant, or if you’ve had a previous miscarriage or ectopic pregnancy, your doctor or midwife might recommend an ultrasound scan in very early pregnancy, often at 8-10 weeks. This ultrasound scan can check for the baby’s heartbeat and work out the age and due date.
