so i havent gotten my period this month! I was originally suppose to get my period around the 19th of november. It currently shows i am “9 days late”. I have tooken 3 pregnancy tests within the last week and couple days and all were negative. I have been experiencing cramps and my back has been hurting alot. One thing i should add is i took a PLAN B 3 days before i was suppose to start my period. My last period was also late due to taking a plan b and having alot of stress due to work. Im not sure if its late bc of that again?? Just worried and thinking alot. I dont feel any other sx just cramps.
