Question about period?

Hello ladies,

Maybe I am worrying too much about this. I am kinda freaking out because my period is suppose to be here soon, and well I think I have been having symptoms of PMS, like back aches, cramps and horrid mood swings. The problem is I am worried because when the well after the week of , which my last period was November 14th. my period, me and the boyfriend had sex, yes he used a condom. Usually I have my period in the middle or more to the end of the month. Should I be freaking out or just relaxing?

Thanks,
