Should I be worried?

So I'm supposed to get my period today. I had sex three times this month protected he didn't cum inside of me and we checked all three condoms. None of them torn or ripped. The first time I was at 9 % risk and the other two times were 3% risk.  I am bloated, my boobs are sore and my legs are killing me. All symptoms from my period but I haven't gotten it! Should I be scared? Or am I just over reacting
