35 weeks pregnant. 1cm dilated 30% effaced. Can sneezing cause further dilation? Scared of delivering preterm. : (

No. 1 cm. Dilated and 30% effaced is perfectly normal at 35 wk. Gestation and sneezing will not cause dilatation or labor. Fortunately for those with seasonal allergies, sneezing is not a cause for preterm births. :) Your concern tells me how lucky this baby is to have you for a mom. Hope this helps and best wishes to you both.
