I can't seem to drink more beer or drinks no more is it possible to be pregnant cause ever time i take a dollar tree pregnancy test its negative.

Two issues: If you cannot tolerate alcohol, that is a blessing, because does not do anybody good. If you are having unprotected sex and are not using any contraceptive, you could get pregnant. If you miss your period by 4-5 days, 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, or IUD. Practice safe sex. Get HPV vaccine.
