My sister is currently in labour

Thursday they called her in for induction, when she arrived she was 3 cm contracting every 4 min but couldnt feel them, so they sent her home to see if she would progress on her own

Friday night they went back to the hospital to check her, her water was leaking started her on pitocin at 10 pm but had to stop because baby heart rate was dropping

Today her water is still leaking, shes 5 cm and they are retrying the pitocin again

If this fails are there any other methods they will try before opting for c section? Shes absolutely traumatized already and im really hoping for her sake this doesnt result in a c section
