period hormones??

I know it's normal to be extra emotional during certain days of your cycle, but it is normal to be more emotional and depressed a week before and (so far) 4 days after your period starts? I deal with chronic depressed normally, but it's just randomly gotten so much worse. I don't know if it's anything to do with my cycle or it's just my depression getting worse on it's own. Can anyone help?
