Thanks for the query.
Better to plan after cesarean section.
As the manipulation during procedure can stimulate uterine contractions and can lead to preterm delivery and also any post-operative infection can lead to chorioamnionitis
Till the surgery you can take symptomatic treatment like taking more liquid diet
, fruits, vegetables, drinking plenty of water, using analgesic
and anti inflammatory jellies etc.
Main thing is you have to avoid constipation
