Help need advice

So I'm 9 weeks pregnant with my second baby and I'm soooo tierd its u real and generally just fell like crap. I'm trying to just get on with my normal day which is house work take the wee one to nursery collect her, shopping ect. I'm struggling so much this time round don't remember felling this bad with my first. I'm also having nightmares which are waking me up at night seen my midwife today and she's done they're normal tests other than a slightly high temp everything is fine. Can anybody give me any tips on just generally trying not make myself fell better.
