two weeks after period, i have sore breasts. the sides and the upper part hurts alot, dull cramping, etc

So i french kissed my boyfriend, i was in my period which was two weeks ago, second day. Suprisingly i didnt have cramps at all. Maybe its because i changed the way i was eating. Anyway. Now two weeks after period, i have sore breasts. the sides and the upper part hurts alot, dull cramping, kidney pain, either full or hungry, tired, i cant sleep normally, i also feel like am breathless when i try to sleep. Could i be pregnant from french kissing? Or is it ovulation? I am so stressed out that i keep on cryinng because i dont want to be pregnant am just 17 please somebody help me. And i cant talk to my parents.
