HELPPP !!!

So I started my period on the 2nd of August and ended the 8th . I started taking birth control on the 6th for the first time . And I take my pills at 10 pm every night . But , on the 12th , I forgot about it because I was at a friends house . So I took birth control for 6 days , on time . And the 7th day was the 12th and I took the pill I was supposed to take on the 12th , I took on the 13th in the morning . But , later on in the day , I had unprotected sex and he didnt cum in me . But we had sex twice that day and I know leftover cum can be in his precum . So then later on that night I took my pill that was on time . So I took two pills in one day . But on the 14th I took take action . My friends told me I didn't have to take the morning after pill because I would've been fine either way . But I just wanted to be sure . So should I be fine ?? I took a pregnancy test Friday and it was negative . And i start my period in 8 days so if I end up missing that and it still turns out negative , is it because my body is completely screwed up for starting bc mid cycle , taking two bc in a day , and took take action ?
