Tightness 5 weeks post c-section?

Hello,

I have had my first elective c-section 5 weeks ago and have only yesterday started to feel quite a tightness when standing up straight on my abdomen, most though in my groin when I stretch my legs apart a little. I am wondering if this is normal part of the healing or if this can mean I have too much scar tissue or adhesions? I am very worried about long term complications/infertility and get upset every time I feel a new worrisome sensation..
