Hello
Thanks for writing to HCM

Yes,there are chances of pregnancy due to unprotected sex in second time.
You can take unwanted 72 but its efficacy decreases after 72 hours.
However it is not 100 % effective even if it is taken within 72 hours.
You should wait for your next period.
If you have missed period then urine pregnancy test can be done.
However ultrasound of pelvis is the investigation of choice to confirm pregnancy.
You can plan accordingly.
Medical method of termination of pregnancy are effective up to 98% in early weeks.If needed you should consult your gynecologist.

Take Care
