Trying to kickstart dilation!

Hey ladies! I'm currently 38 weeks, I was told by my OB on Friday that if I wasn't progressing with my dilation by my next appointment (this coming Wednesday) I'll be scheduled for a c-section to happen on February 3rd! I have only been dilated to a "fingertip" for about 3 weeks. This is my second pregnancy, my first was a c-section because I couldn't get past 1 cm. I was hoping for a natural birth this time around. So I just took one 1,300 milligram tablet of evening primrose oil, and am currently drinking raspberry leaf tea. I'm really hoping that these things will help me dilate! I'm not really worried about getting baby out right now, I would just like to avoid surgery! Have any of you ladies had any luck getting your cervix to open up with these methods or any other method? I'll try just about anything at this point 😅
