Vasectomy reversal

My husband just underwent vasectomy reversal surgery the 16 of this month. We are ttc right away. we haven't done the deed yet but will as soon as we are able;which also happens to be the time I'm fertile! I've not been on any birth control for about 6 years now. My last birth was 2 years ago and shortly after that my husband got a vasectomy. Any idea on how long it could take to conceive? The surgeon said my husband had active/swimming sperm already!
