back ache & cramping

Savannah
I'm 5 weeks today and for the past two weeks I've been having cramping in my lower stomach, not as bad as a period but it's noticeable, and sometimes when I lay on my sides it hurts on the side I'm laying on, I haven't had any type of bleeding or anything but I just wanted to know if that's normal. Because I miscarried my first pregnancy at 6-7 weeks, and had no cramping up to the time I miscarried. Idk I'm just scared. And I've had really bad back aches when standing. Is this normal?? Help!
