I keep forgetting to take my pre-natals: Advice?

So lately. I haven’t been taking my prenatal. I’m just concerned if it’s going to affect my baby’s health. I know it’s essential. But with my first child, I did take them due to my iron. But now with my second. I forgot every time. And when I remember to take them. It will be when. I have to take my medication. Or when I see them in front of me. And it like almost every other day or sometimes I skip like a week. I have been eating healthy. No sugars. Caffeine like I would with my first. It’s all naturals. How can I keep up with my prenatals. I even set an alarm. But when I turn it off I just forget to take it. I’m currently 22 weeks.
