Anybody have this happen and not be pregnant? trying to not get hopes to high

Me and boyfriend had sexy time right before my period last month, my menstrual then was super clumpy and not normal then stopped after day 3. now this week has been my "fertile week" breasts have been super sore for a good 4 days now, im suppose to ovulate today but they have been super sensitive to touch and burning(mainly my nips)... any suggestions? my breasts have never hurt during fertile week before. should i have hopes??
