I took ipill on Saturday and did intercourse...

Treatment :
First of all primolut its not effective for emergency contraception for your case if yout not already under contraception before you will be in risk to be pregnant and for that if your period delayed more than7 days better to do pregnancy test .
According to time 20/01 and you are in risk to be pregnant we will not recommend to use other kind of emergency contraceptives as ellaone and levonell thats why you should wait and watch but because of stress is going on with you and estrogen tabelt present in primolut can your perido delay but for this leg pain if no swelling or cough thats a clue your period going to be started .
