I'm 54 days late for my period and taken home test and blood tests but they all cam up negative. is there a chance i could still be pregnant. i know a few people who were getting negative tests until they were 3 months pregnant?

Ultrasound scan: It is unlikely that you are pregnant. Your doctor can do an ultrasound scan that would show the fetus by now, if you were pregnant. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
