If you mean a regular plural noun as opposed to an irregular plural noun, then the answer is that a common noun can be a regular plural or an irregular plural; and a proper noun can be either a regular plural or an irregular plural. The difference between how a regular and an irregular plural noun is formed is usually based on the origin language from which it came to the English language. A common noun is a word for any person, place, thing, or idea. A proper is the name of a specific person, place, thing, or a title. The regular plurals are formed by adding an 's' or an 'es' to the end of the singular noun to make it a plural noun. The irregular plurals are quite varied. See the link below for a simple step by step list for using irregular plurals.

It might simply mean that your period is being irregular this month. You'll know how likely that is by how regular they usually are. If you've been having sex, it probably means that you were pregnant but had a very early miscarriage. About 2/3 of fertilized eggs miscarry or fail to implant, often before you know you are pregnant. Be more careful.
