period concerns?

ok so as you can see I just got off my period on the 4th. I lost my virginity on the 11th and have been bleeding slightly ever since. I am not for sure if my period has came early but as you can see it’s not supposed to come till around the 30th.

If my period did come early bc of the sex would I still get my period on the 30th? I’m just concerned bc if it doesn’t come I don’t want to freak out.

(I know upcoming period is long that is why I am on the pill)
