Is it normal to be this tired?

[cheeseisnice]

I'm really at a loss with what to do about my fatigue right now and I'm wondering if there might be something else at play, such as low iron.

I'm 14 weeks pregnant with DC4. It's been a while since I was last pregnant and I seem to have forgotten how I felt back then. I don't recall being particularly tired, but I'm absolutely knackered all the time at the moment.
I slept 11 hours last night, dropped the kids at school this morning, slept another 2 hours, got the kids home after school and fell asleep on the sofa for 3 hours, got up and made dinner and tidied up....and I want to go to bed again.

Is this normal or should I see a doctor? If some of you have also experienced this, when can I expect it to pass? Any tips for powering through until such a time as my energy returns?

Do you have good sound sleep or very light sleep?
I'm 26wks, and still sleep 11-14hrs per day. I have poor quality of sleep as I have lots of dreams and awake. I feel like floating everyday. No energy at all. My doctor says my blood pressure is a bit low. My iron level is ok. I also have anxiety. Maybe you are not as complicated as me :p but it's worthy telling your doctor about it if you feel not right.
