CS before and currently pregnant

Hi mommies! I need your insights in my current situation. I am 16 weeks pregnant today. And I am still breastfeeding my CS baby who is now 23 months old. Sometimes, I feel pain in my CS wound. I am worried, about my current pregnancy now and being a cesarian mother. Pls help... Anyone who had the same experience? What are the possible consequences? And my things need to do for safe delivery? Thank you so much mommies!
