Help ASAP! Late period talk

So my boyfriend and I had sex two days before my period was due. I’m now 5 days late for my period. He didn’t cum and we used protection. We didn’t fully have sex either but my parents showed up so we had to stop and get changed before they knew and walked in. I have also been stressing a lot with school. I have all the symptoms for getting my period like acne, headaches, cramps, back pain but I still haven’t gotten it. What should I do? Am I pregnant? Any advice?
