Missing period on birth control

I’m on yaz and I’m on day two of my placebo pills and I still have not gotten my period. I’ve had sex but he pulled out wearing a condom. Other than that we were messing around one that and he fingered me with the possibility there was cum on his fingers he also rubbed the head along my clit. I’m getting white discharge currently but no blood. Should I be worried I haven’t missed a pill but sometimes I’m an hour late
