Hi, I have question about late periods. My girlfriend hasent gotten her period for at least 5 dayz, we had sex a month ago(we used protection) since dat time, she had her period for only 3 days and after she started 2 pee a little bit of blood . It lasted about for a couple of dayz then it went away. And now she hasent gotten her period, im just realy worried she might be pregnant. Can you tel me what is wrong with her ?
