Bfp but worried

So today after being 5 days late I tested and it is positive!! Bitter sweet feeling I had an ectopic in early December and I’m scared this one will be too I’ve had sharp pains that’s why I was so nervous to text. I’m hoping that there just normal pregnancy pains and my mind is playing tricks on me ! I updated my glow to show pregnant but it’s going off of my previous pregnancy and showing I’m 16 weeks and that wouldn’t even be correct I would be way further along does anyone know how to update ?
