BFN 11 dpo

M

I got a BFN on the 20th. According to my other app I was supposed to start that day, it never came. I started cramping the 15th for a couple days. Now I don't even feel like I'm gonna start? It feels very wet down there with some discharge but no spotting or anything. Am I out this month since I got a BFN??? Why would I of cramped the 15th for a couple days then stop? it never does that. I normally cramp the week before right up until I start. I am now on cycle day 28 when it's normally 25. I'm so confused this cycle. I also ovulated later this month I normally ovulate CD 11. let me add the test I took was a dollar tree test if that matters at all.
