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..
A false negative result is when the test says you are not pregnant but you are. This can be misleading and when using home pregnancy tests you must be very careful of avoiding any factors that may cause false results. The major reason for a false negative test is that you took the test too early.
