Hi,Im Myce. I am regular and normally having a period monthly. My last period was November 19,2015 a heavy flow one. I expected my period earlier or just late for a days to 1 week on December .But until now,I never get my period.We do unprotective sex. I don't have the sign of pregnancy,I took a pregnancy test earlier this January 4,2015 first hour in the morning but it was negative. Any one can answer mt concern? Thanks
