second line?
Bishop score 5
membrane sweep
PGE2 / oral misoprostol
maternal oxytocin
cervical ripening balloon?
when is balloon catheter preferred for IOL
when maternal risk of uterine hyperstimulation (tachysystoles)

uterine rupture
NICE CKS - ‘baby blues’

follow up
NIPT
blood test
analyses small DNA fragments that circulate in the blood of a pregnant woman (cell free fetal DNA, cffDNA)
cffDNA derives from placental cells and is usually identical to fetal DNA
analysis of cffDNA allows for the early detection of certain chromosomal abnormalities
sensitivity and specificity are very high for trisomy 21 (>99%) and similarly high for other chromosomal abnormalities
