3 years ago I had a second c section with my daughter. Once I started my monthly cycle, I have been in terrible pain. Days I cannot even get out of bed to take my oldest daughter to school. The first 3-4 days of my cycle is very heavy. I have lower abdominal pain in the center and right side. I can press on my left side and no pain but it hurts the center and right. I also have this pain that runs up the center of my stomach and in to my belly button. I have taken so many over the counter medications, from advil, midol etc to tylenol #3 s with no help. I will eat and it triggers knife stabbing pain in my belly button. Any help would be appreciated.
