Hi,

My gf had her period last week and it ended last friday, lasted for 5 days. And last friday we had unprotected sex. She said its safer than other times cause she just had her period. But i didn't ejaculate in her.

But yesterday, she said she was having her period again. There was blood. Yesterday and today.

Is it really a period again? Can it happen twice in almost a week? Or is it something else?

Thanks.
