Hi! i just want to share my problem right now.. i had my period last January 12,2017- January 16,2017 and today when I woke up, I went to the comfort room to pee but when I saw my undies, it has a blood, like a normal menstruation and I feel some cramps.. im worrying that I might be pregnant, I had sex last January 19,2017 , 2 days after my period ends. And we have a protected sex. What might be the cause of my bleeding and cramping. Thanks!!
