pill help

About 2 months ago possibly a little longer I started the cerelle pill
Had sex many times and had normal period after 
But the 25th last month I was away with my partner and had my period roughly 2 weeks before hand, had sex and it came to the Sunday we had sex again we noticed blood when he pulled out 
after that I had light bleeding for few days like I had mini period 
I haven't come on this week like planned and came off the pill just under 2 weeks ago
Didn't know if the bleeding could actually be mini bleeding and the sex has made me loose some lining so my period will be late because of it or coming off the pill might have messed my hormones and will make it late 
I did take basic pregnancy test and was clear but panicking now why I haven't come on
