tired

So I know everyone is different but since it's most common to be getting more energy going into your second trimester, well I really haven't been super tired through my pregnancy until the past week or two. I'm 12w 3d now and I'm exhausted. I can barely stay up until 9-9:30 anymore. And yesterday I had slept for 9 hours the night before, I went to work and wasn't busy at all so I really didn't even do anything and by 2ish I was soooo tried. By 7:30 I was struggling to keep my eyes open. So has anyone experience extrem fatigue later on?
