Thank you for posting your question here, I will try to answer it to the best of my abilities.
The chances of you being pregnant are pretty small, after all you used condoms and contraceptive
It is very well possible that you're period is early this month, that can happen sometimes.
Another reason could be because of the contraceptives, they are known to cause irregular bleeding in some women.
So the way it stands, I doubt you're pregnant. But to be on the safe side take a home pregnancy
I hope this answered your question.
