Pregnancy test. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. It is not clear why you were prescribed Progesterone but typically one has a period after stopping it. Your doctor will need to evaluate your low back pain, abdominal pain and legs pain as all 3 are complex issues.
