Kinda long, but possible rainbow?

So I misscarried on September 9th this year. I had my D&C on Septermver 19th. I have an autoimmune disease where I react when my progesterone rises with a skin rash.. I get it EVERY month I ovulate. I also have painful ovulation so I'm pretty positve I ovulated on october 5th come october 19th I started my period we were hoping for rainbow before my next cycle but I had my period for 3 days medium flow which is a little unusual for me.. the. I ovulated on November 5th same symptoms rash and pain in my lower abdomen. I also confirmed this time with an ovulation test so here I am 10 dpo and got this..

Could this be it? I mean I have had negatives right before the period on 10/19 the insert says test for hcg as low as 25.. I'm just hoping this is our rainbow but I'm so terrified at the same time.
