Period?

So the last time I had unprotected sex was in December but I got my period, full 7 days. I've only had sex 4 times since then all protected with a condom (It didn't break)...My period is suppose to be here sometime around Monday or Tuesday but I'm not getting the usual signs my period is around the corner. Normally I get tender breasts, little cramps, and headaches. My boobs only hurt a little last night and a lot this morning, but now I don't really feel a thing. What do you think? Am I going to get my period? What do you think?
