I’m sure Mary felt silly... explaining her story about an angel appearing and the Holy Spirit coming upon her.

Why?

Joe already had his visit:

Matthew 1:19-21

And Joseph her husband, being a righteous man and not wanting to disgrace her, planned to send her away secretly.
But when he had considered this, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not be afraid to take Mary as your wife; for the Child who has been conceived in her is of the Holy Spirit.
"She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins

Joe was the only person who noticed her baby bump... there was no gossip in this society?
