12 DPO!! help?

So I'm 12 dpo today, bfn with fmu this morning. I have had mild dull cramping kind of like AF cramps but not, seem lower. I have had them for at least 3-4 days, with today being the most noticeable. I ussually have bad cramps with AF so I know these seem different. Possible to still be pregnant? I have a 30-32 day cycle. Ovulated on cycle day 17. Just curious if any ladies had these too?!
