Sperm test - low motility

My husband had a sperm test done and we got results. While count and morphology were normal his motility was low (it was 9% and should be around 32-50%). Have any other women had this experience? He is taking Fertilaid (which is a male vitamin supplement that is supposed to help) but I am worried. We are TTC #1 and have been trying for 6 months. It's good we have an answer but also scary. Thanks ladies. Baby dust to you ❤️
