Not sure if pregnant or stressing to much

So my boyfriend and I had sex last Saturday on the 12th of March and at the end he said he cummed but he was wearing a condom when he pulled out after there was cum on his bed and on my vagina as well, we found that the condom broke so the next day I took the emergency pill within 24 hours after of having sex and I went to the doctors the day after that  and explained and my doctor said if I don't get my period when I expect it (19-22 March, in between those days) I should come back, anyways today is the 19th and I haven't gotten it and I'm just worried that I may be pregnant or the pill didn't work, help please
