Welcome to HCM,
In a regular menstrual cycle of 28 days ovulation generally occurs on the 14th day of menstrual period.
One can become pregnant due to intercourse done on or around the day of ovulation.
You had sex on 11th day of menstrual period. The 11th day of menstrual period comes under fertile period for pregnancy
If your menstrual cycle is of 28 days duration, your next period is due on 13th August.
If your period is delayed for more than a week, get pregnancy test done.
If it is positive, take action accordingly.
