That would make more then five months. almost  six. the amount of time it took for conception to birth for Diana. Actually, it was longer than that.

From what I said above:

2: She had the "Affair" with Nick in "Blonde Ambition" Season 3, Ep 22

3: Adalind gave birth to Diana in Season 3, Ep 14, BEFORE her tryst with Nick

Adalind gave birth in the Winter, not that long after the New Year and Monroe/Rosalee were married in the middle of spring
