HSA card

Arianna • High school sweethearts 🧔🏻👧🏻🎀 TTC #2 for 3 years #pcos 🤎🌈 Baby #2 due March 2022, FINALLY 🤎🤰🏼🌈

I know I can use my hsa card to purchase prenatal vitamins and or pregnancy test/fertility kits but I am wondering if I am able to purchase those online and be able to use my card? (Amazon for example)
