9 months postpartum

I had to have an emergency c-section to get my little girl out as she was stuck. I have felt pretty good since about 6 months postpartum but over the past few weeks, I have been having alot of pain where my scar is and just generally feeling sick and tired all the time. I know it can take a while for your body to fully recovery but I guess I'm just wondering whether all this is connected or is it just a coincidence? I'm also not pregnant again as I have just finished my period.
