seems to be an intestine problem but make sure are there any other symptoms and if there are write it down then see your doctor once no harm in meeting the doc as it near the reproductive system.
Good Luck
The pain does not mean that something is really bad or really wrong. It could just be muscles in there. If it does not get better see a doctor. But do not over worry this.
Lower abdomen pain could be an intestinal problem our a problem with your reproductive organs like an ovarian cyst. You won't know what it is until you see your doctor about it, so make an appointment. :-)
