Hello. I had an ultrasound yesterday, after CS it's been almost 2.9 years. The doctor said that the scar is very visible, thick. I was surprised that it immediately catches the eye. I asked how bad it is? She replied that it's normal, apparently the reason is that I had a hematoma on the scar from the beginning (discovered on the 2nd day after CS). The doctor didn't say anything more about it. And I'm worried. Has anyone experienced this? Is it bad in case of pregnancy? We don't plan to, but we wanted to know what if pregnancy occurs, will the scar be able to withstand the load, considering that my children weigh +/-
