I take an oral contraceptive pill that I've been using for two months now. I missed one pill earlier this month and had unprotected sex that night. I doubled up 24 hours later when I realized id missed the previous pill. Now I stopped taking the pills so my period would start like usual. I took the last one on Sunday and only started very lightly bleeding on Thursday. Barely anything by Friday morning and Friday evening absolutely nothing. This is very unusual I usually have a very heavy flow that lasts the full 5-7 days. Help!

It is possible, that you are pregnant, even if you take every pill exactly right, the birth control pills are not 100 percent effective. So pregnancy is very possible.

You need to wait about 10 more days, and do a pregnancy test, if you do not get a period.
