What Should I Think??

My breasts always start to get very sore a week before my period but now I'm 11/10 days away and they already hurt. My one nipple hurts and then the side of my other boob hurts. It's too early for pregnancy signs isn't it?! My ovulation day was the 1st and the only time I had any physical contact with my boyfriend was the 31st and it wasn't even sex just possible precum scare that couldn't result in pregnancy seeing as it would have had to be inderted through fingers. Is this just early PMS?
