Was the use of BCAA branched chain amino acids affected by scoking and possible weakness of the tablets before training or on an empty stomach on non-workout days?

For more than half a year he has been using Novynette birth control pills. On the 13th day of taking the tablets, I had had a sming ness and then turned into a slight bleeding. Due to my lifestyle and work, I took the tablet 1-2h earlier or later from the set time (19:00) I know that this may have contributed to spotting. My questions are: 1. Has the effects of the tablets been weakened by the discrepancy in the hours? Is there a chance of pregnancies? 2. Was the use of BCAA branched chain amino acids before training or on an empty stomach on non-workout days affected by scoking and possible weakness of the tablets? I've always kept a time interval. I do not take other medicines that weaken the effect of contraception. 3. Do I need additional protection until the end of the blister? I have already arranged a visit to the gynecologist. I've done two tests, they're negative. Thank you very much for your reply. The whole situation makes me extremely stressed.
