Who got early cramps after a bfp?

Hi, I've had a mc in April(early at 6wk). I got a faint line yesterday(14dpo). But I now experience cramping since yesterday feels like af is coming. My btt stays high. I tested again today it came out even more faint but there's still a line to see.. no af/mc yet. Driving myself crazy here. Do you have any experience with cramping after testing lightly positive? is there a way to see if this it's normal or start of a mc?(except for bloodloss of course)
