I'm 5 days late with pain. What should I do? I'm five days late and I have always had a 28 day cycle since I got my period 10 years ago. Today I woke up with pain in my left side.

It . It is very important that you take a pregnancy test. If you are pregnant, then any abdominal pain must be taken very seriously. While many women get "round ligament pain" when they are pregnant, you also have to worry about tubal pregnancy, so it is very important to get medically evaluated if you are having pain.
