Can Bruising & Pain In Stomach And Nausea Be Normal After Hysterectomy?

Hi there. I had my hysterectomy laporoscopically, Bladder sling, anterior and posterior repair. I am 54 years old. I am trying to stay in bed and take it as easy as possible. I was sent home with very little info. Things I have experienced so far: black and blue stomach, pain in the groin on either side which felt like ingrown hairs which I found were the incisions the bladder sling. Bleeding. Abdominal pain especially when I sit down on toilet it feels like my stomach is ripping open, like when I was pregnant. I feel like I need to hold my stomach when I move. What I have new today is nausea and dizziness but no fever. Are all of these normal? I am very concerned about the dizziness that started today.
