Pregnacy despite emergency contraception

Patient: On the combined pill I stopped for a month then started up again at the beginning of my menstrual cycle with the 7 inactive pills and after taking one of the active pills I had unprotected sex. this was also the day after the end of my period and I read getting pregnant then is difficult. I also within 48hrs of the incident took emergency contraception and continued normally on the pill. is it possible I’m pregnant? (I also had bleeding and some discharge a couple of days after taking the emergency contraception)

Symptoms: dizzy, nauseas and muscle spasms

Doctor:
