I am due to have my period this week ( im on the logynon pill), i usually get it by tuesday, now its thursday. I had unprotected sex on saturday night and took the morning after pill on sunday morning, and i still have not got my period yet. i took a home pregnancy test this morning which was negative therefore i figure that counts out being pregnant earlier,could it be running late due to these factors, i had not had previous sex for a few months, i also deliberatley missed my period last time for a special occasion. i have also been pretty stressed the past month, can some one please ease my worries????
