hopeful and nervous!

Hello everyone! I'm relatively new here, I've kept myself to myself and has a nose around as often as I could. I'm pretty shy and find it difficult to talk to people. But I need help! my husband and I have been married 2 years in March and we have been trying for a baby for just over a year. Well today, he came home on his break for lunch and I decided to take a test, it was super faint at first and over the next two hours got darker! I'm really nervous and I don't know how to feel or think! Is this definite? What do I do next? I can't tell anyone and my best friend and I have fallen out so I have no one. Please someone make me feel better!
