By far, the most common cause of secondary amenorrhea is pregnancy. The test you took was negative, but I would repeat it to be sure. A second common cause of secondary amenorrhea is weight loss.

Likewise, if you made millions in 2017, whether from cryptocurrency, your job, or any other source, you are probably at the highest tax bracket, currently 39.6%. Itâs important to understand that these are just marginal rates applicable to you as an individual, and that assets (like cryptocurrency) often qualify for a better rate, known as the capital gains rate.
For 2012, trusts reach the highest federal tax bracket of 35% at taxable income of $11,650 (except for capital gains, which are taxable at a lower rate). By comparison, the tax rate for single taxpayers on taxable income of $11,650 is only 15%. The highest federal tax bracket of 35% does not apply to most individual taxpayers until their taxable income reaches $388,350. In addition, many states also tax the income of trusts.
