okay so i just had unprotected sex now here's the thing, he was using steroids but is now on his off cycle and has been for two months i think, i also took my last pill yesterday so my period should come shortly... i am conflicted on whether i should take plan b, which can delay my period ... but won't it screw with my pills when i start to take them again after i am done my sugar pills? or should i just take the plan b ? i am so confused on what i should do... please help ?
