Surviving extreme fatigue

I worked a really long day yesterday (I own my own business) and woke up this morning exhausted and haven’t barely been able to do anything. It feels like I’m getting over a flu. Migraine, nausea, inability to eat much.. I have mild abdominal tightness as well. Im afraid to do much because of the mild cramping I am feeling.. worried I pushed myself too far. 😖 I’m 7w6d. Any of you all feel like you’ve had to just take a day at this stage of pregnancy? I feel so guilty because there is so much I should be doing but my body is demanding I sit still and rest 😔
