Yeah...I was the same...I was so hanging out for 2nd trimester and the "happy hormones"...

They took a while to kick in...probably didn't start until about 18 weeks...and just got better and better...18-26 weeks was just great...I felt pretty invinsible, actually!!!

At 27 weeks, I'm now starting to get a bit tired again...but nothing like 1st trimester...I guess that's to come!

Hang in there...it definitely does get better...
