Need some positive vibes.

Took 3 pregnancy tests tonight all 3 coming back positive. According to my last period I would be 5 weeks 5 days. I'm freaking out my husband doesnt really want anymore. We will have 3 under 3. My oldest will be 2 in Feb and youngest is 4.5 months. How did everyone do 3 under 3. Please give me some reinsurance, not even sure how to tell me husband.
