Penelope cant be lady whistledown

Did anyone else notice in S1 when both Eloise and Penelope are wondering how does a lady become pregnant. None of them succeded in finding out. And in the same season Penelope as Whistledown is writing of Daphne and Duke's honeymoon wishing them stamina for their honeymoon in S1E6. To me it is quite unreasonable that despite her being unnoticed enough to gather all rumours easily, she is lady whistledown. She is simply too naive to be commenting on marriage and courtship.
