Bfp or evap line



So I miscarried 2 months ago, first period after was right on time and I'm currently a week late on my second. Have been having a few symptoms sore boobs, nausea, so took a test this morning on the off chance. This line appeared after about 2 minutes, although because it was so thin and slightly off centre I was wondering if it could be an evap line. Any thoughts?? Anyone had this before?? Thanks 😊😊 xxx
