Please help... anyone

I recently got off birth control and ttc... I’m 11DPO and for the last 2 days, I felt abdominal cramping.. not PMS like.. more like in my uterus and lower back that feels like pulling and a heavy feeling. That went away. No spotting either. I tested today for pregnant and it was negative. Is it too early? Please any advice.. if you ever gotten pregnant, how many DPO did you get a positive? ☹️
