I’m so nervous right now

ni

I’ve been taken tests and posting them and i took one yesterday afternoon and it was in fact a BFP! no doubt about it. This morning i took another one to see if it got darker in the morning and the line is basically not even there. It’s a different brand of test but it just shattered my heart i am praying my little sticky bean is healthy and i don’t lose it. Has this ever happened to you guys before? Is there still a chance and i could be ok?
