I can’t believe it i guess!! Help

I took the top test five days ago and the bottom one today. I’m over a week late on my period but i guess I’m sort of in denial 😔. We have been together for almost ten years and have a 4.5 year old and 1.5 year old together. And I’m terrified!! I’m so nervous to have two close in age. Am i crazy for feeling this way?!?!
