Your period cycle is 29 days . Your last period date was 30 May.
Your ovulation date should be 13-14 June (14 days before the next period date).
You had intercourse on 19 June, that was 5-6 days after the ovulation date.
By that time you were in the safe zone. On top of it you have taken emergency contraceptive. So the chances of pregnancy are very low.
Emergency contraceptive can delay your periods by a few days (3-4 days).
You should do
beta HCG test on 19-20 July (21 days after the date of sexual intercourse). By that time we would have catered for irregularities of the periods.
