Could I be pregnant? On pills but started pack 6 days late

My pills are 24 actives, 4 placebo (yaz), my last pack's placebo pills started on 29th Oct, withdrawal bleeding started around 31oct/1st nov, supposed to start new pack of active pills on 2nd Nov, but only started on 7/8th Nov. During which, had s*x with boyfriend on 3/4th Nov, came inside. Missed 10th’s pill and was late for 11th’s pill, took both pills on 12th’s morning at 6am. Had s*x on 10th and 11th and bf came inside both times. Could I be pregnant? I have no idea if i ovulated cos i started my pack late, anyone knows how to calculate? when is the earliest i can test? Thank you so much:(
