Its my first pregnancy!

Currently in my week 6 of pregnancy! Its weird that i feel so tired and sleepy. I am totally not a heavy sleeper or a lazy person. It makes me mad that i keep falling asleep anywhere. ? And my appetite is crazy, i will eat small portion but i feel hungry within the next hour and it just goes on. Tried forcing myself to eat but i'll end up vomiting. Glad theres no morning sickness so far but the breast tenderness is giving me real pain. Nevertheless, i am totally enjoying this journey! ?
