Last year it was the case that BTNPlus only had the rights to women's games played with a Big Ten team as the home team - Wisconsin, Minnesota, Ohio State. Assuming the same would hold this year for the expanded list of WCHA teams, none of the games this weekend have a WCHA team hosting. And looking out a couple weeks can be misleading, because they are notorious for being tardy adding games and links to their list/calendar.
So the first one you should expect to see is Lindenwood at St Cloud on Oct 1st (I hope), but not listed until later.
Note that Penn State hosting St Lawrence is on the calendar for this Thursday and Friday. If you see those, then you're A-OK.
(in the meantime, you could go back and watch the replay of Wisconsin vs defending national champs Kentucky in volleyball, on Sept 10. For the first two sets, Wisconsin actually made them look bad, which was fun, and then the next two sets were just dogfights - comebacks, blown leads, 'overtime'. A whole different kind of fun.
