premature.
if your period comes on early does that mean that you are not pregnant?
yes pioneer means early
That depends on what you mean by "early on".
Early
what does the same mean
Yes.. the same signs that usually mean your period is starting can also be signs of early pregnancy, if your period is late, I recommend doing a home pregnancy test. ~pawsalmighty
No
sign of an early winter
If you mean early as in WWII then there were none.
early childhood; the beginning or early existence of anything
Yes, the early 1800s is the same as saying the early 19th century. The 19th century encompasses the years from 1801 to 1900, so the early part of that century refers to the first few decades, specifically the 1800s. Therefore, both terms refer to the same time period.
You got your period early!
