Pregnancy test after trigger

Al

Hey ladies! I need some help. I had my trigger on CD13 (July 31) I didn’t take any tests until Aug 10th which is the top test and you can barely see the line. I didn’t test again till Aug 12th and it looks like the line is getting darker. I have my blood test tomorrow but has anyone experienced this and been pregnant? I don’t want to get my hopes up but I had a miscarriage a year ago and I want my rainbow baby. Thank you!!
