Just had a Chemical pregnancy I think

Amy • Married 5-20-12 to my love since `08 ❤️ Our 🌈 Lucas arrived 5/16 - baby #2 became an 👼🏼 in 9/19

Can someone explain this process? I’m sitting on the floor crying after having my doctor confirm my pregnancy 3 days ago, I just took 3 tests and all are negative. What should I now expect over the next few days? Hubby says no more trying so we’re done with our quest for baby #2. I was 4 weeks 2 days today.
