Cramping at 7 weeks

Marissa • Married.
I'm 7 weeks along and im experiencing mild cramping. I'm reading that it's normal because the uterus is expanding but I want to see what all the mommies on here this as well. Ever since I found out I was pregnant I had mild brown spotting. Last night was the first time I felt cramps and it came with some red blood (mild) same amount as always. I'm just kind of nervous..
