pregnant????

about a week ago I had unprotected sex with my boyfriend and he cane inside me. As soon as I got home from his house I took two of my chryselle birth control pills and went to bed. when I woke up the next morning I took another 2, and another 2 that night when I got home. I took another two the following morning and them resumed taking them normally. Since then I have experienced cramps, white creamy discharge as well as spotting. prior to having sex, I had missed one pill and I was already spotting as it was as a result of breakthrough bleeding. I need advice & someone who is educated to inform me whether I might be pregnant or if this is just a result of me taking so much birth control.
