Missed Pill! Help!

Just wanted some advice, I take the 21 day pill, I had my 7 day break and started my next pack on Thursday 7th April and this Tuesday so the 12th I forgot to take my pill so I took two on Wednesday!  Then today I have started to have break through bleeding!!
I know missing one pill is usually ok, I was just worried about the bleeding and the fact it's in the first week?
I have taken my pill yesterday and today, am I at great risk of getting pregnant at the moment?
Thanks
