Yes | No Thank you! In both of my pregnancies, I took tests 1 - 2 days after my missed periods which both turned out negative. I waited about 3 more days both times and then each turned out positive. I guess it just depends on your hormones... by now, you should be fine trying another test. When in doubt, see your doctor.
Flavonoids are a large family of polyphenolic plant compounds. Six major subclasses of flavonoids, namely anthocyanidins, flavan-3-ols, flavonols, flavanones, flavones, and isoflavones, flavonols are the most widespread in the human diet. (More information)
Among flavonoids, flavonols are the most ubiquitous in foods. The main representatives of flavonols are quercetin and kaempferol (Figure 2(f1)). The flavonols are primarily found in onions (up to 1.2 g/kg fresh wt), curly kale, leeks, broccoli, and blueberries. Red wine and tea also contain up to 45 mg/L flavonols.
