Pregnancy test: It is time that you do a home pregnancy test. 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. Practice safe sex. Get HPV vaccine if you are less than 26 years old.
