My question is can Plan B mess with your cycle even almost two months down the road? I took Plan B almost 6 1/2 weeks ago. I experienced a period within about 2 weeks of initially taking the Plan B. Here I am about a month later expecting my period again and I usually have symptoms, sore breasts, some cramping but I have NONE of those and I'm already a few days late for my regular period to start. No sexual intercourse has taken place since the incident of the condom breaking when Plan B was taken and I have taken a pregnancy test this week just to be sure and it's negative (test taken with first morning urine, about 6 weeks after condom broke after having sex). So technically this would be my second period AFTER taken Plan B, is it normal for it to cause you to be late or not to come at all? Thanks in advance.
