maternity grant question!

I applied for the Maternity Grant (Sure Start) as I'm on Universal Credit on maternity leave. However, my husband has a new job (yay!) but it may mean my benefits are stopped. Fair enough if he earns enough but what I'm wondering is, does that mean I won't get my Maternity Grant I desperately need? When I applied I was 100% eligible but if they stop it before they pay the grant will they cancel that too? Can't find anything online. Thanks in advance
