There is no way for us to tell you if you are or if you are not pregnant. Unfortunately, we can't do pregnancy tests here, and we can't do the lab work. You are playing the waiting game now. There are many reasons for a missed period, some we know of, and other times the reason is completely unknown.

Exactly there are so many reasons, have you lost a lot of weight recently?Are you eating right?
Or maybe you just missed a period this can be common.
