Possibly pregnant?

Kimberly
Hi guys, i was suposed to get my period today. My last one was on September 5th. And I had unprotected sex on the 31st of last month when I was fertile. Im not sure if it's just late, but my body defiantly feels off. My breast are super sore, I've been getting headaches, a bit nauseous., eating a lot more then usual, and get nauseous with certain foods or thinking about certain foods. The weirdest thing is i always get bloated when I'm about to get my period and I'm not at all...
