Experienced abdominal pain where i couldn't walk straight without pain. i couldn't lift my leg to my chest. my period was few days late?

GP review : Best you get seen by your GP as soon as possible as this could be a Gynaecological or GAstrointestinal cause, both of which could be emergency requiring surgery

See doctor urgently : Period late = may be pregnant +abdominal pain means need to exclude nasties like ectopic pregnancy. Unless you haven't been sexually active. At the minimum needs an urgent pregnancy test and best to have your tummy examined

When? etc: As the other's have suggested, Dr's are always highly concerned about the risk for ectopic pregnancy (an early pregnancy that develops in the wrong place e.g. the Fallopian tube) because if missed it can be very dangerous. But, there are a very wide range of possibilities for your symptoms. A more detailed history +/- physical exam +/- urine or blood tests are needed to be sure.

? Ectopic pregnancy : Signs and symptoms ectopic pregnancy: Light vaginal bleeding Nausea and vomiting with pain Lower abdominal pain Sharp abdominal cramps Pain on one side of your body Dizziness or weakness Pain in your shoulder, neck, or rectum If the fallopian tube ruptures, the pain and bleeding could be severe enough to cause fainting.

Your question: is not clear....If you are having the pain you describe NOW I would go to a ER or Urgent Care center. Abdominal pain when walking and pain when trying to lift leg may be signs of PERITONEAL iritation (eg: Appendicitis!!) Hope this is helpful! Dr Z
