Help needed!!

Okay so long story short my friend broke up with her boyfriend and gave me 2 month worth of the pill I've took the whole packet and now waiting on a bleed but I'm sure they've not worked I've google what this pill is and there's not much information online about it me and my partner have had sex numerous time last month where he's finished inside of me but my normal period is 11 days late I've had a sore right breast where I can't even touch it and the random times where I feel really sick
