Pwede naman, pero depende talaga sa doctor at sa condition mo ngayon, kasi kahit na same date ng first CS mo, bawat pregnancy is different, especially with a 6-year gap! One of my mum friends actually tried to schedule hers on the same date as her first but the OB advised against it kasi may certain health considerations na dapat i-check muna. I'd suggest talking to your OB about this plan so they can assess kung feasible at safe talaga for your body after 6 years, better safe than sorry, diba?
