12 DPO-cramps for pregnancy or period!?

Hi all! I have been experiencing cramps the past couple of days. I am expected to get my period on Friday and I'm 11 DPO today. For those who have been pregnant, did pregnancy cramps feel identical to cramps you get right before your period? Like a mild cramp in my uterus area. I did get a shadow line on three different types of tests today, but I feel like my period is coming :(. Any advice?
