Threw up birth control... chance of pregnancy?

I’ve been on Nora be for like a year. Last month I started feeling nauseous after taking my pills (closer to end of month) I think I threw up maybe a couple times last month but I ended up spotting dark clumpy (TMI sorry) for 4 days. Then I know I missed a pill starting week 1 of my new packet but took another one right away (I’ve been throwing up 15-30 mins after taking) then I threw up again a couple days later but was so drowsy I ended forgetting to redoes and went to sleep. Now the following day me and bf had unprotected sex (second time this month) and I also cramped pretty bad that day. I’m about to finish week three but I notice I actually missed another day Week 3. Is there a chance I could be pregnant now?
