hello,
thank you for using healthcare magic,
first of all chances of getting pregnant is almost nill if you had taken postinor within 72 hour of unprotected sex and its second dose after 12 hour.. plus it looks like you had intercourse on 8th day which is not fertile day if your cycle is of 28 to 30th day .. your partner didnt even ejaculated so dont worry about
pregnancy.. chances are extremly less.
nause vommoting and bleeding for 3 to 4 days after taking postinor is normal. it will subside after few days and if not consult gynecologist..
in case you do not get your next period take urine pregnancy test after week..
take care...
