guilt over morning after pill

I feel terrible. My fiance’s condom broke and i was exposed of course. i was still on my period so there was a low chance. but he said now wouldn’t be a good idea to take any risks. so i had to take the morning after pill. and when we got home.(after i had taken it) he said how he wouldn’t be afraid if i was pregnant because i am the woman of his dreams. and how beautiful our children would be. even though its birth control. i feel like i destroyed something that might have happened. is that silly?
