I second the above posters! All I did the first trimester was nap, then I had a burst of energy that lasted up until week 28 and now I'm 37 weeks and again all I do is nap! lol
Hopefully it will start to get better for you going into your second! It should.
It comes and goes for me so far, I'm almost near the ending of my 1st trimester
It came and went for me. Second trimester I had a lot of energy, third i have none!
18 weeks tiredness is starting to go nauseated feeling still there blah me
