Is it finally time? Implantation cramping?

Me and my husband have been trying to conceive for almost a year. We recently had sex 3 times on the 2nd. According to the app i ovulated on the 3rd, but i know that doesn’t necessarily mean it’s accurate. (I havent been keeping up with my ovulation lately)

Anyway, all day today I’ve had mild cramps in my lower abdomen. But it’s only been 6 days, so I was wondering if anyone knew if it would be too early for implantation cramps to happen?
