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..
Signs of pregnancy: Nausea, fatigue, loose bowels, abdominal pain or even vaginal bleeding are not reliable indicators of pregnancy. The best way to know for sure is an at home urine pregnancy test. Since you are so close to ovulation, if the 1st test is negative, you should repeat another one 1 week later.
