Afterbirth

I've been worrying myself about the pain of the stiches from birth, I don't know what to expect my mother had c-section with both me and my sister. Mensturating and stiches seems all so painfull, I am one to overthink things but I don't have anybody to reasure me anything positive. Any help or experience tips/advice would be muxh appreciate and could help me to stop worrying so much.
