Welcome to Healthcaremagic and thanks for the query.
By this time you must have enrolled in an antenatal clinic and getting the folic
acis, iron, calcium preperations as well as immunisation and your doctor must have clinically evaluated you for the absolute indications of caesarian like contracted pelvis, short stature, any bad obstetric histry, placenta previa
etc. You need to be physically active, and enroll yourself in yoga
classes for specific antenatal exercises.
Take care. All the best.
