Hi, I Have Had A Very Unlucky Week And As

Hi, I have had a very unlucky week and as a result I am in a difficult situation. My last period was on the 1st of December. I had unprotected sex with my boyfriend on the 7th of December and took the EllaOne morning after pill the day after.. We did this even though we weren't sure ejaculation had happened, just to be safe and as advised by the chemist. On the 13th we were having sex and the condom broke and as a result he ejaculated into me. I once again took ellaone, but I threw up within an hour. I was given a second dose and it has stayed in my system. I am wondering what my chances are of pregnancy at this time as I am very anxious.
