how pregnant mums does it ?

Congrats on your pregnancy! Keep in mind that all pregnancies are different and there are so many mums like you, who find their energy depleting towards the end of the pregnancy. Make sure you are taking in enough nutrition and resting enough when you're home. If you take public transport, you might find it easier to take taxis just for the last few weeks. However, it might be also good to mention to your doctor that how you feel. If it's anything out of the ordinary, they will be able to advise you.
