It is completely normal to experience fatigue in early pregnancy. Small amounts of caffeine are safe in pregnancy and can hit an increased sense of energy, but you may have just an increased need for sleep as your body adjusts to pregnancy. Craving certain kinds of food is also completely normal. You should see a health provider for routine prenatal screening tests to rule out any medical problems and begin taking prenatal vitamins, if you haven t done so already, but in the meantime, it s just ok to accept you need more rest! Good luck!
