am i possibly pregnant?

$$

my last period was april 27th, im currently 7 days late on my period and all of the 7 days ive been having SEVERE CRAMPS !! usually at night between 3am - 9am it wakes me up out of my sleep everyday but still no period. is this a sign of pregnancy? im honestly terrified to take a test because 7 months ago i miscarried at 7 wks .. literally 5 days after i took the test i began to miscarry which let to a long depressing day in the emergency room.. i guess im just a little afraid to get my hopes up. any information on what i've been feeling? what it could be? its not likely for me to be any more than 3 days late on my period.
