Does cramping always mean you’re out?

Just looking for some positive stories, though I know my period will be here on Tuesday. We’ve been TTC for over a year, in that time we’ve had an ectopic and a miscarriage. I usually start cramping about a week before my period, sometimes only 5 days before, so I don’t bother to test early because I assume my period is coming and it does. My question is, should I always count myself out? Has anyone had cramping in the days leading up to your period and then turned out to be pregnant? I know there’s implantation cramping, but I figured that would happen for like a day and then stop, I always have consistent cramping for several days leading up to AF. This past year has been so challenging, and I almost hate how in tune I am with my body that I don’t even need to test, I just know what’s coming. Baby dust to all the mamas out there trying.
