Always tired and exhausted

Ogechi

6weeks 6days gone, baby number 2 but I don’t understand how I feel. I get tired easily. Feel nauseous if I eat anything not very spicy and hot. Didn’t feel any of the this in my first pregnancy. Have this strange feeling it could be twins…..and it’s scary as shit. I don’t have the mental capacity to take care of twins😭😭😭
