I had unprotected sex but used HD pills four times my mistake

Patient: Hello,7 days ago I had unprotected sex with my partner for 3 days,from the first intercouse I got 2 HD pills and during these 3 days I ate 2 HD pills every 12 hours and we had unprotected sex in between too,but I made a mistake of taking HD pill 4 times (8 pill at total, taking 2 pills every 12 hours), 2 days after I had syptomns of menstruation but it fade away in following days,So what should do now? should I wait till calendar menstruation time? does taking HD pills 4 times instead of 2 makes it effectless?
