Hi doctors, My wife has experienced a preterm pregnancy at 26 wk . Unfortunately the baby did not survive. So doctor suggested for the cervical stitch for next pregnancy. So as my wife is pregnant now, stitch operation has done at 14th wk after NT scan report. Doctor had prescribed dydraboon, ritodrine, folvite and cansoft-cL. Any progesterone injection did not suggested. Can you please guide us that is it okay what the medicine she is taken?
