Ovulation after miscarriage

I miscarried at 5 weeks after TTC for 7 months. My doctor said we could start trying right away bc of how early it was. I am on cycle day 46 and have been testing daily with let down after let down then today I got this... Please tell me it's time to baby dance! Or maybe tomorrow? I have two sheets of BFN, this just got me so excited. I want our rainbow baby so bad. I've been so depressed and it's like today a glimpse of hope came through. I hope it doesn't take us another 7 months :/
