11 weeks & cramping

Is it normal to have cramping at 11 weeks .. I am so scared I have no bleeding but when I got up from bed my stomach was cramping it was like a sharp pain I haven’t felt cramps since I first got pregnant and thought my period was coming that was at 7weeks I am high risk atm due to a tear in my placenta dr said it should heel itself by 12 weeks I see my OB tomorrow however if this is not normal can someone let me know so I can go to the ER this is my first pregnancy…..
