Feel like a shit mom

I'm 6 weeks 2 days pregnant, and this nausea has me laid up in bed basically most of the day despite the remedies I try. I have an almost 3 year old, and it breaks my heart that I can engage with her. My husband is extremely tired, he's doing everything at the moment. But she's always been so attached to me, and I just feel such extreme guilt having to tell her no when she wants to play with me...my mom came to pick her up today so she could have some fun, and she basically ran out of the house. She usually asks me to come, pulls on me, says she will miss me, etc. But not this time 😭 am I ruining our bond? Anyone else been through something similar? I feel like absolute shit.

Thanks for the advice ladies, here's a photo of my girl at her gammies house having fun without mommy 😭💜
