“I know not man”, A woman intending to have children with her fiancee does not respoind like that.

Mary wasn't intending to have children with her fiancee, as you say, but when she was married. She knew 'knowing a man' meant - knowing him intimately.

"When Joseph woke up, he did what the angel of the Lord had commanded him to do. He took Mary to be his wife but knew her not until she had given birth to a son. And he called his name Jesus".

Apparently, she was not intending to have children at all, because there was nothing in the Angel's speech to indicate the conception was to occur prior to the marriage. You can go around saying "thou shalt conceive in thy womb" to every engaged to be married girl on earth and you will not hear a response "How?".
