13 dpo.. negative 😔

Af is due Sunday/10th and I feel I'm already out this month. 😢 Just took a blue dye and it was stark white. Feeling real down because my best friend wasn't trying and got 4 bfp's yesterday, 3 days before her expected period. I had a pinching/cramping feeling on 6,7 &8 dpo, been crying over every little thing. Sore bbs, hungry like crazy and a little nausea here and there. I guess this isn't my month. I had a miscarriage last year around this time at 7 weeks and I didn't find out until day of missed period so i keep telling myself that im not out until af shows but its so hard. Anyone else get a bfn on 13dpo and go on to get a bfp days later? 😔😔😢
