5 weeks and I feel miserable

5 weeks 5 days pregnant today and I feel so horrible I can barely get up. Is it normal for it to feel so intense? How do I deal with this? - SO exhausted. Even just getting up and walking to the bathroom leaves me winded. - No appetite/ food aversion but constantly hungry. - Shaky, dizzy, nauseous (no morning sickness yet) - lower abdomen bloating/ hardening and cramping. It’s like I can feel my uterus stretching up.
