Okay so my AF was due January 11 2017 . Never got it . My last period was December 14 to 17 . My breast are tender and sore been throwing up on and off and my breast have grown a size . Now this is where it gets tricky I had a positive hpt four days ago . But today I got a blood test done and the results said negative . Now I have had issues in the past with my last two pregnancys didn't find out till I was a little over three months along . And when I found out with them the pee test were really faint . I don't know what to think . Could I still be pregnant ? I feel like **** breast sore breast nausea vomiting no period
