Answer: It’s completely normal to feel tired, especially in the first 12 weeks of pregnancy. That's when huge changes take place in virtually every system in your body, making you feel extremely tired. Throughout pregnancy your body works hard. But the biggest effort comes in the 1st trimester. That's when your baby's major organs are formed, and the placenta, your baby’s life-support system, starts growing. Your hormone levels and metabolism are rapidly changing, while your blood sugar and BPlevels tend to drop.Tiredness and low energy levels can sometimes mean that you're too low in iron , which is fairly common in pregnancy.Being tired and run-down can also make you feel a bit low. Occasionally, being exhausted and having trouble sleeping can be sometimes mean depression It’s different for every mum-to-be, but you’re most likely to feel very tired in your first trimester and your 3rd trimester. In your first trimester, fatigue is often one of the symptoms of pregnancy sickness, along with nausea, loss of appetite and sometimes vomiting.
If feeling and being sick are disturbing your sleep then you’ll feel even more tired and irritable. Try to get as much rest as you can, because fatigue can make nausea and vomiting much worse. It will help if you listen to your body signals to rest, eat a healthy diet, some exercise and try to get into a schedule.
