Am 11 weeks preg. I still toss and turn at night with force. That can't cause miscarriage, can it? Worried since baby would be bigger now.

Fetus is safe. Your fetus is well protected inside your uterus by chorioamniotic membranes, amniotic fluid, the muscular wall of your uterus, your abdominal muscles, tissues and skin. Therefore "tossing and turning at night with force" will not cause a miscarriage or harm your fetus now or later.
