Robin • Mommy to Phoenix 8.8.19 my beautiful rainbow baby boy!

So I took the bottom test late last night around 11 and woke up and took another test around 8am and it looked the test above the darkest one. I was hoping I was about to get my positive but I'm a little unsure. I'm hoping it will get darker again tonight but just wondering if this has happened to anyone else?
