Quick question ladies

Mary • Mommy to Finnegan, Aelish, Mairead 👶🏻🍼 Nurse 💉💊 Happy 😊

Now I know this is positive. Definitely darker than when I first found out at 10 dpo last Saturday. I was supposed to get Aunt Flo supposedly Wednesday. Technically I’m 16 dpo. When is the test line supposed to be darker? I’m just super anxious that I’ll have another chemical or miscarriage because I had a chemical last month. Any insight I would greatly appreciate it. Thanks ladies.
