10dpo and ideas??

So I'm 10dpo today, frer was bfn. Took an ovulation test just for the hell of it and it's a pretty dark 2nd line (pic below). Any ideas? I did have some minor cramping on 8dpo and 9dpo. But nothing else. Usually I have really sore breasts by now until af shows. Thinking af is on her way and I'm out this month which makes me so sad!
