Fatigue and lack of energy

Hello ladies. I am in the second trimester, 14 weeks, and my only problem is that i feel tire all the time. I just want to lay down and sleep. Even when i work i am so week and so unwilling to do things. As a person i am always active and full of energy but with this second pregnancy i feel so much different. Please help me what should i do. I do not like coffee this time so that excludes one alternative. Please help 😄😄
