Is severe heartburn and chest pain right before a contraction normal? 27w 3d. I was prescribed pills to help stop contractions 3 days ago but they didn't relieve any pain last night or this morning. Plus 3 days ago I was already 1cm. I know you can be 1cm dilated for a while but I'm still worried :/
