I'm 5 days late cramping headaches past two weeks and have diahrrea is it possible im pregnant?

Depends: If you had unprotected sex since your last period, you could be pregnant. Do a home pregnancy test. If the result is negative, repeat the test 4-5 days after that. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
