Could I have gotten pregnant?

Patient: Could I be pregnant? I’m on the pill yes and last Tuesday I missed one and I’m pretty sure I’m not protected for 7 days after that. So on the Saturday night me and my boyfriend had unprotected sex. My period was due on the Saturday but because I missed a pill last week I was supposed to skip the inactive pills this month and not have a period and i havent. And its the Tuesday now and I haven’t taken any pills since saturday night. I read on my pill leaflet thing that if you have unprotected sex and then miss pills there is a high risk of getting pregnant. And my question is, do you think I could have gotten pregnant? I know I have to wait 19 before I can test and it’s too late for emergency contraception. I was just wondering how high the risk of getting pregnant is?
