Worried I may be losing my baby again

I miscarried September 10th and waited a couple weeks to make sure my levels were back down before we started trying again. I found out I am pregnant this week and have been testing every other morning because I am crazy nervous. This morning my digital was still positive but my line test was lighter than before. I'm trying to stay calm but it's hard not to think the worst. I got my blood drawn yesterday and will again Monday to see if my levels are going up. Keep us in your thoughts please!!
