Rainbow fears

Marli • Lottie Mae norm 3-23-20. Liam Thomas🌈 born 4-7-17. Angel baby 5-4-16. Hubby & I married 11-1-14. Have two Pomeranian `babies`.
Got my BFP today at 8 DPO. Which is super early and has me so paranoid it's not real. This is our Rainbow after losing our first little one at 11 weeks 3 days May 4th. 
That's the hardest thing I've ever been through. And I just want this baby to be ok. I just want to keep it safe and have it stick and be healthy. It's all I want.
