Cramping AFTER ovulation?

have any of you had a dry spell where you thought u didnt ovulate cuz there was no ewcm? but had a ton of cramps even after the days you were due for ovulation still cramping? we baby danced 3 days before, then i had no signs i was gonna ovulate for some reason. i always have TONS of ewcm that whole week. this week. nothing! just a ton of cramps. this morning i had a tiny strand of stretchy cm and that was it. but i am getting even bad BACK CRAMPS. not just pelvic. back... thats odd... could i have conceived? any of you have these type of *O* in a cycle and got a bfp??
