Me and my girlfriend were having foreplay at that time her period was due . we indulge in lots of grinding etc where my male part rubbed her vagina with great effect but I did not penetrate her..after around 65 hours she took emergency contraceptive becoz we were worried that she might get pregnent... she experinced spotting and very light period after she took plan b now after 15 days she is feeling dizziness and tiredness ... could she be pregnent?
