First trimester help!

Ch

I am about 8 weeks right now with baby number three. Let me tell y’all, I am struggling. I have the worst insomnia at night. Before this pregnancy I was in bed and asleep by 8:30. Now, I am up until midnight, 1 am even after taking Tylenol PM. I have two children that are home with me all day while my husband works. Almost two and five so I can’t exactly sleep all day. All day I am physically exhausted. Head pounding, nausea, and I can’t help but take at least three naps in between a load of laundry and making dinner lol I can’t get anything done. I have to run errands on my husbands off days in order to get anything done because I can’t even load the kids up in the car from being so week and exhausted. I don’t remember experiencing this with either of my other pregnancies. I need some advice. Some remedies for this exhaustion. Any other mama’s experiences this? How long did it last for you other mama’s? What can I do to help?
