I Took 2 Emergency Pills. I Now Know I Shouldnt

I took 2 emergency pills. i now know i shouldnt have . The first one i took said the reviews werent the best the went and got the name brand plan b . The first one was the next day, the second one was on the 5th day. I don't have a certain day i start my period. He didn't cum in me. I'm just worried bc even though he wiped off the pre cum. I'm just still worried. We didn't full on have sex. It was a just a thrust 4 times. That's all a had time for. I'm worried. I just today about half hour ago had pinkish brown discharge. I also have minor cramps. Is this because of the extra extra hormones or is it a possibility in pregnant?
