I got fatigue for the whole first trimester, then it got much better. Third trimester it tends to kick in again, I have had fatigue come back around 31 weeks. But at this point I am so big, and having a harder time moving around and sleeping well so I am not that surprised.
It was one of my first symptoms, hit at around 4 weeks and got progressively worse throughout the first trimester. Lightened up when I hit the second, but I hear the third trimester can be bad.
My fatigue hit before I knew. We were ttc. I felt fatigued pretty badly starting around day 26, and got a positive on day 30. Really I wouldn't remember except I had an intern following me who had followed me before and I kept apologizing for being slower walking around and climbing the stairs.
My fatigue hit at about 7 weeks and didn't leave til 14-15 wks. Now I get occasional days where I'm just beyond tired. I'm 22 wks now.
For me, fatigue kicked in around 4 weeks, but we were active during ovulation, so I already suspected the reason, although it wasn't confirmed until 6 weeks.
I'm 25 weeks and I'm just as tired if not more tired than I was in my first trimester. I exercise and eat right but cannot get enough rest. All pregnancies are different too!
It varies but for me I was so nausea in the beginning and could not sleep at all. Now I'm 30 weeks and I wanna sleep all the time lol
