Okay, My b/f And I had unprotected sex(no birth control), Im 3 weeks late, tender breasts, nauseus and at times actually throw up, constipated, moody, feelings of bloating, and I took a tests yesterday and it came up negative, before the test I peed all day, and drank tea, and orange juice about an hour prior to taking the test. Could all the drinking and taking late in the afternoon affected the result?
