Hello good morning. My GF took nordette as ecp april 22,2014 4 pills 11:07 am then another 4 pills at 11:07 pm we had unprotected sex last april 19,2014 not really penetrating her but i cummed outside her vagina im scared that some of it got to her vagina. So im worrying right now because its been 13 days and her expected menstruation is today at may 5 (regular 28 days period) she still doesnt have any bleeding. But she has been experiencing PMS for the past 5 days (abdominal cramps, painful breasts, pimples) Can she be pregnant? Or can her period be delayed? Pls help thank you.
