Ma'am and mom

I know that my pronunciation skills are not good, so I hesitate to speak loudly in public.
One day I saw a woman drop her ID and not realize it. I ran into her and said "Excuse me, ma'am!". In my head, I wonder if she misunderstood me as having said "Mom".

発音がうまくありません。分かっているので公衆で大声で話すのをためらってしまいます。前にIDカードを女の人が落としてそれに気づいてなかったので「すいません！」と追いかけたのですが、頭に中ではmomって言ってるって思われたらどうしようって思ってました。。。
