Is it normal to feel super sleepy in your last month of pregnany?

I feel more sleepy during the first trimester while during the last trimester I am not feeling that sleepy. It could be due to you wake up more frequent in the middle of the night to urine/drink water and thus make you more sleepy in the daytime. Try to cut down the water intake at night so you will have to go toilet less frequent.

It differs from woman to woman. I was very active in my last trimester and didn't feel particularly lethargic or sleepy.

thanks
