I am new on triphasil and started the pack on white pills row because I was not on my periods.on the 7th day I had unprotected sex and now m on my 3rd red pill and have not got my periods yet can that mean I am pregnant?? can triphyasil protect me from pregnancy on the 7th pill??

This is a REALLY confusing birth control to take.Did you start the way you should have started, according to the instructions?

Regardless, I do not believe that the hormonal birthcontrol was active when you had intercourse. Thus there is a chance that you could have become pregnant. I would consult your doctor, I am not sure if you're supposedc to get your period on this pill or not so the usual advice of wait until you miss your period by two weeks might not apply. Your doctor should be able to sort this out.
