Asking for prayers *Trigger Warning: miscarriage*

On December 26, I got a faint positive pregnancy test. I took another on Dec 28, and it looked the same. I just took another today and the second line still is only marginally darker than Dec 26's test, but I also took a digital today that read "pregnant". I've had 3 early term miscarriages, all that started with faint positive lines, that never got much darker. Due to my history of miscarriages, my obgyn said he'll see me Tuesday instead of waiting until week 8 or 9 for the first appointment like he normally does. The digital test reading "positive" gives me hope, but I'm still terrified of having another baby leave me too soon. I would appreciate prayers for this little one and hopefully I can hold this baby in my arms and not just in my heart.
