Could I be pregnant?

My boyfriend came to see me during spring break and we had sex without any protection but he pulled out every time. We did this in December to but I didn’t get pregnant. But my period is 5 days late and I am worried I may be pregnant. But I have sore boobs and cramps so I think my period might be coming. I am 14 almost 15 and I am scared because I don’t know what my parents would do. Any opinions?
