I'm sorry you are dealing with this. A swollen belly at this point is pretty normal. Not sure about the stomach pain. Occasional pain or discomfort would be pretty normal at 8 weeks. But the pain should not be frequent or severe. "Terrible pain in my groin and in my left leg" does NOT sound normal. It could be nerve damage. Unfortunately, some surgeons tend to dismiss any complaints that could be surgical complications. Be a "squeaky wheel" as this should be investigated. Best to you!
