Exhausted all the time

I've reached the start of my 2nd trimester and I swear I had more energy in my first. If I hadn't gotten a positive pregnancy test or my sonogram, I wouldn't have even known I was pregnant. I felt great. But now it's like all of symptoms are catching up to me now. I feel so exhausted even after just waking up. I can't stay up past 9 pm anymore. Is this or did this happen to any else? I heard the 2nd trimester is supposed to be when I have the most energy. I'm feeling the opposite.
