Your query is a bit Ambiguous. From what I assume, you seem to be feeling that you are pregnant though your period is not due yet.
Whatever be the case, nothing can be commented upon unless you wait for the period to happen normally. If you miss your period and if it is delayed, then it is probable that you are pregnant.
Else, these symptoms do occur even in the absence of pregnancy
'Wait and watch' would be apt here.
All the best.
