Ovulation post

Gracie

So today makes 7 dpo (days past ovulation) and I’m getting these period like cramps and breast tenderness, I know it’s normal signs for a period or Pms but could this be implantation, I ovulated on July 5th and that evening me and my husband had sex. My cycle is 33-35 days. This month will be our second time trying. Any advice? Xoxo
