I am 35 yrs old expecting baby #3 and am 13 weeks 4days. And I am extremely Tired!!! I can barely stay awake all day. In fact most days I have at lest 1 nap. But then there are days I can stay awake all day but then can't sleep at night. I thought this would have passed by now that I am into my 2nd trimester. HELP does anyone else feel this way???
