Contractions at 29 weeks

Tylisa

I’m 29 weeks but will be 30 weeks tomorrow and had to go to the er cause I kept feeling sharp pains in my stomach. Turn out I was having contractions. Nurse checked me to see have I dilate and I haven’t dilated at all. They gave me a shot to stop my contractions but the sharp pains are back again today. Have anybody felt this pain before this early and what happen.
