Start of 2nd trimester and so tired!

Buhl168

I read that fatique is pretty common in the first trimester not necessarily the 2nd. Aside from the beginning of my 1st trimester, I've been pretty energetic. But this week, I've been so tired. I'll usually run errands, jog or do chores around the house after work, but find it hard to do that. I've been napping for 1 to 2 hours and wake up feeling like I barely slept. Is anyone else going through this? Is this normal? And how long will this last! I need my energy back! I'm approaching 15 weeks.
