Cramping and back aches 9 days before AF

Miss Hawai’i

BD when I first saw ewcm at Cycle day 13. For three days, I have been getting these light cramps with ewcm, almost like AF is coming. But AF isn’t due until 2/20 and still haven’t spotted. Took an OPK two days ago when I first started feeling the cramps (cycle day 24 and 9 days before AF due), but I barely have LH in my system, since there was hardly a faint second line.

Has cramping about a week before AF was due lead you to a BFP?
