Generally, it is not advisable to travel into/out of the US on a non-immigrant visa while you immigrant application is pending. You may have been fortunate in the past with entering on a B1/B2 without a problem but it does not mean that this is a guarantee in the future. CBP may stop and question you in depth about your true intent for entry, which can cause serious problems down the road for your ability to immigrate. Is the risk worth it? You are the only one who can decide.
