SomeVar is a variable of type Variant. Since a variant can behave like any data type, we can make it look like an array, which is exactly what the ReDim statement does.  After it is executed, SomeVar becomes an array! Of course, we could create a 2 dimensional array with.  ReDim SomeVar(9, 9)
If the egg is not fertilized, hormones stimulate your uterus to shed the lining at the end of your cycle. This shedding is your period. Experiencing a heavy or even a normal period means that you cannot be pregnant, since your uterus has shed its lining instead of maintaining it to sustain a fertilized egg.
During early pregnancy, it is not uncommon for a woman to have bleeding or spotting. This bleeding can sometimes be mistaken for a period.
