C section pain / muscle weakness pregnant after c section

Hello all!

I had an emergency c section with my first around 26 months ago, I’m now pregnant 9 weeks + 3 days
And having some days where my c section feels really painful, also feels like the muscles are really really
Weak below the c section / around! It’s a struggle to stand sometimes and standard paracetamol doesn’t help, also a lot of back pain!

My bladder is adhered to my uterus and I had endometriosis excision 5 months ago, my uterus was adhered to my stomach wall, I guess I’m just wondering has anyone had anything similar?? I had a scan last week and all is good and seeing my OB this week but just looking for any support / advice

Thank you :)
