Very short period ?

Morning ladies! So I normally have a 6 to 7 day period this cycle it was two days. We did BD every other day in my fertile period and if anyone caught my post in the "expecting period 4/16" post I had unusual cramps the week before my period and none when I got it for those two days.  I am going to test today just to see. I just wanted any opinions or if anyone had anything similar happen. Maybe my cycle just changed a but but ver unusual for me
