Rainbow after the storm right before my birthday?!

Kristy • Married the love of my life🤵🏻👰🏻4/21/18. Lost our angel baby at 11 weeks👼🏻 12/6/18. Had my rainbow baby boy👶🏻 3/27/20. Lost our 2nd angel baby boy at 21W3D 6/3/2022 👼🏻. Pregnant with rainbow baby #2.

Yesterday I took a test that came back negative (totally expected it). I’ve felt extreme fatigue for the past 2 days and my boobs are starting to feel sore. Today I’m 7-8 dpo and took a test with second morning urine. Wasn’t expecting to see anything but I kinda do! Could this be the start of my rainbow baby?! My birthday is tomorrow. Could this be an early birthday present?!
