Took 5 test, postive. suppose start period tomorrow. having cramps by also lower stomach and down area. need advice?

What's your question: Pregnancy tests are very accurate once you've missed your period although I suppose they could turn positive one day before your expected period. Many reasons for cramps, including bladder infection, sexually transmitted disease/infection, menstrual pain, and/or miscarriage. Since you've had 5 positive tests, go see Family Doc, GYN, Planned Parenthood or local city/county health department.
