"I felt very happy to see a couple who were holding each others' hands and crossing the road, in the evening, very carefully, as the lady was pregnant"

It made me very happy this evening to see a pregnant couple holding hands as they (very) carefully crossed the street. (It doesn't sound good to use "very" twice so close together)

I was very happy to see (I was very happy when I saw) a couple in this evening who were holding each other's hands and crossing the road very carefully as (because) the lady was pregnant.
