Anyone else have cramps before BFP?

S

So every single month I start getting cramps around 8-9 DPO and they go on and off until my period comes, so that’s always my clue that I’m not pregnant, and it’s disappointing cause pretty much a week after ovulation I figure I’m out this month. I also get slight diarrhea around 8dpo everyy month. Anyone else get cramps that early and end up with BFP?
