Help!

Hi ladies, I’ve had a chemical pregnancy before, so I’m extremely paranoid about this pregnancy! Today was the day I’m due on, but I’ve been getting positives since around 10dpo, line has gotten darker each day. This morning I tested and the line is the same as yesterday mornings line... it hasn’t darkened! It’s the same as yesterday. I’m so worried this is going to end in another chemical and il start bleeding anytime!

What’s everyone’s opinion on the line progression, the last two are the ones I’m concerned about:(

Many thanks xx
