Contractions 4-5 mins apart, 2cm dilated?

Emily
I'm 33 weeks tomorrow with d/d girls have been having contractions 4-5 mins apart for about 2 days now. Went to the hospital found out was dilated 1cm Tuesday, wed 2cm. Cervix still closed. Got two steroid shots to help with babies lungs. Anyone else have contractions that close but no labor? Doctors said I may just contract regularly until delivery?
