BFN. Am I out or still possibly in?

Cora

I took a test today and it was BFN. I am due to start in 2 days and I had some brownish color on the toilet paper when I wiped about 3-4 days ago and nothing since then. I’m not having any of my normal PMS symptoms and have had really low cramping that is much milder than my period cramps as well as lower backaches, headaches and I feel like I kind of want to gag at certain times during the day and I have spells of lightheadedness. Am I out for the month or could possibly still be in?? I was another baby sooo badly 😕
