Im having faint dull cramping and presure in lower abdomen ?

Go see ur Family Doc: You didn't mention your age. Regardless, you need to see your Family Doc, GYN or Planned Parenthood for evaluation & testing. Perhaps you have bladder infection. Or maybe pregnant? Home pregnancy tests are available w/o prescription at most drug stores. They're accurate once you're late. And let's not forget sexually transmitted diseases/infections if you engage in unprotected sex.
