Long post help!

I stopped taking my birth control pills which were jencycla. It's a mini pill. I stopped over 3 weeks ago and I am currently on CD 40. My last period was August 21st. I had some very light spotting for like 3 days right before I stopped the pill but I didn't count that as a period. I haven't had any withdrawal bleeding or anything since I stopped the pills. I have had unprotected sex multiple times since I stopped it and I'm aware that I could get pregnant from that but I am okay with that so it's not an issue. I was only on that particular birth control for 2 and a half months. Was I on it long enough to mess my cycle up this bad or could I be pregnant? I took 2 pregnancy tests at 2 and 3 days late and they were negative. I am currently 11 days late. And I haven't had any signs of a period or pregnancy except bloating which is normal for me.
