Hmmm...I think your pregnant or the only other reason why you would get a positive preg test is if you had a rare ovarian cysts which causes a positive pregnany test. Or you are just so early in pregnancy and your hcg levels arn't that high in your blood yet. If I were you I would go back in a week and get a blood test again, I know that a week is sooo long away, but that is the only thing you can do. And if the blood test comes back negative, then I think you arent pregnant, and something may be wrong which you should then get checked out. But there are no foods that can cause a positive pregnancy test, so It is either your preggers or you have a rare ovarian cysts. I hope I helped hun!!!
