Okay I've took plan b twice the first time I bleed a couple hours later... this time I took it nothing happened no bleeding no spotting.it's been a week!! my period tracker says I start my period in 5 days. I've been cramping off and on. Has anyone took plan b more than once and had different side effects. Shouldn't I have bleed like the first time? Does it sound like I could be pregnant. I'm cramping kinda high also... I couldn't find anyone that this happened to...
