My last period was April 18th, before that period my last one was December 28th. The reason for such a long cycle was because I took a plan B in January. I went to PP to make sure everything was okay because my cycle lasted so long and they assured me that it was from plan b. So now I'm waiting for my period to show up and it hasn't. Could this still be plan b messing with my cycle? I am stressing myself out over this which I think could also maybe be why it's delayed. If anyone has advice or can relate, please do so :)
