2 sugar pills left and still no period. after 2 yrs its never been this late. is this normal or should i take a pregnancy test?

Depends: If you had unprotected sex since your last period, do a pregnancy test. If the result is negative repeat the test 5-7 days later. 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.
