So afraid

I got a positive test today (or three, five. Whatever...) and I'm so happy but I'm so afraid. I can't bring myself to download glow nurture yet. I've had 3 miscarriages so far, and I'm afraid to feel excited or hopeful. I haven't told my husband yet. I want to get a blood test done and then another and maybe one more to make sure my levels are rising. I was put on Femara this cycle to help me ovulate earlier and more strongly. I still ovulated late, though my LH strip was the first true positive I've had. I don't know how to feel right now :(
