I just had an HCG blood test done 3 days ago at what I believed to be 10DPO and it was at a 4 (meaning negative). Definitely thought I was out for the month. But I didn’t start my period today like I should have so I took a test just to see and got this at what I believe is 13 DPO. Mind you, this is a cheap test from Walgreens and the lines look really odd to me. I’m confused 😢
