Best prenatal vitamins?

My partner and I are going to start trying for our second in the very near future, and I'm wanting to start taking prenatal vitamins in preparation, but I don't really know anything about vitamins at all, like which brands should I look for, and which ones I'd want to avoid, etc.. and is there any significant difference between regular vitamins vs gummy vitamins? Is one type better than the other? I was looking at a few different ones the last time I was at the grocery store, and they were all a bit on the pricey side. I used to have some a number of years ago, but it's been so long I can't remember what brand they were. I don't remember them being so expensive either, I was at a Kroger though, so that could explain the higher prices, but if anyone has any suggestions or recommendations to steer me in the best direction, I would appreciate it very much! (Also, thanks in advance for the help/advice!)
