Pregnancy after loss

So I just found out I was pregnant yesterday and I'm freaking out. I just had a miscarriage in January and all day after I left the office, all I could think about is what if something goes wrong again? Will I be able to handle this again? Should I even get my hopes up? Should I wait to tell my husband? Should I tell him right away? A MILLION questions has been flooding my brain... I could barely sleep last night... I haven't told him still... I want to wait and do something special to tell him. He was really sad when he found out we were losing he baby, and I can't even think about telling him if something is wrong again. I also feel this guilt, like I'm going to fail. I think I just need some encouragement...
