pressure, opinions please!

Emma

So my period is due friday, my husband and i we’re actively trying for a year and tracking everything then i decided too just go with the flow, but today i got three times of pressure and pain right in the middle of my uterus that made me bend over & it wasn’t like my period cramps. Can anyone tell me what this may be. Could it be implantation cramps? I’m 10 dpo today!
