Implantation cramps?

Sarah
Ok so I'm 7dpo today.... I had quite bad cramping earlier that lasted about 3/4 of an hour.... It felt like af was about to start, no spotting or bleeding though and af is a week away.... Boobs have started to get sore this evening.... Trying not to think about it to much and get my hopes up but was wondering what you beautiful ladies think about it!?
