Prenatal Gummies

So in the beginning of my pregnancy, before I even knew I was pregnant, I had really bad nausea to the point where I couldn't eat anything at all. I was so miserable because of it. Two days ago I started taking the Spring Valley gummies and I noticed that my nausea went away. When I googled if prenatal's do that, all that was being said was that they actually make it worse unless it has B6 which fights off nausea but mine has B12. Idk, I'm just wondering if it's possible or not and your guys' experience with this. Thank you! x
