5 weeks and 2 days

So I'm pregnant....YEY!! Saturday night I had an argument with my husband. I was/am so upset. We didn't talk all day yesterday. So I had no appetite yesterday only ate once, was lifting heavy laundry baskets, and cleaned with bleach...wasnt too strong. But I don't want to risk anything. We finally talked before bed and we are both very upset and trying to get passed this. But I am so worried that anything I did will somehow affect Little Baby. I cannot have another MC. My first appointment isn't until mid December and I'm just worried now.
