5 weeks pregnant and cramping

Sa

This is my third pregnancy this year, and the first two ended before 7 weeks. I'm now 5 weeks today and for the past few days I've been lightly cramping on and off throughout the day but mostly at night when I lay down. I can't pinpoint if it is gassy pain or uterine pain. Is a lot of light cramping normal? I'm freaking out 😔
