anyone's so not understand them being tired?

okay so I'm 8 weeks pregnant and I've got the worst fatigue ever. worst than my first pregnancy, and a lot of the time I wanna sleep, but the thing is my boyfriend calls me lazy when I do and gets super pissed. it's my day off today and he's already yelled at me for still being asleep at 11am. like its my day off? why can't I sleep in? and then he'll complain that we don't spend enough time together because of it and I'm like we live together how do we not spend enough time together? but then when he wants to go out and I get upset, he goes the opposite direction and says exactly what I've been saying "oh we live together I see you all the time" I just don't understand what I'm doing wrong. I'm tired and I can't help that, shouldn't be be more understanding?
