A single-cell organism or plant that feeds on simple sugars that are converted into alcohol and carbon dioxide through fermentation. Yeast is used as an activator to start various reactions necessary to produce alchoholic beverages and baked goods. In alcoholic beverages, it is a key enabler for the fermentation of grains resulting in the creation of alcohol and carbonation common in wine, beer, and other beverages.
I am having pregnancy symptoms (nausea, tender nipples) but I got a BFN (big fat negative) on my home pregnancy test. Those could be pregnancy symptoms, and you may indeed be pregnant, especially if you had intercourse during your fertile time and took that pregnancy test before you were really late..
Pregnancy tests have certain instructions and before you make the diagnosis of a positive pregnancy test make sure that you followed all instructions. Most manufacturers suggest to read their test after 3 minutes and to NOT READ it after 10 minutes. Once you have a negative test after 3-5 minutes THROW OUT the test. Any positive test appearing only well after that time is inaccurate and cannot be considered positive. But a false positive pregnancy test can also happen after an hCG injection like it happened to Kim Kardashian.
