PlatinumGirl, For what it is worth keep stacking, but stack the more generic bars as the premiums are much lower. You said that you have been stacking for a month and that you were buying for $35 an ounce (I presume), a month ago the Silver spot price was ~$22 an ounce, so I will guess you brought some (semi) numismatic coins, Perth Mint perhaps and those are good, particularly if you will want to sell for profit at a later date.
I started stacking Oct 2015 so I'm not that much ahead from you. My goal is to get at least X oz of silver per year and I am already past 1 'years' worth. While I would like silver to stay low for a much longer time than it has, i also know that there will be fluctuations. I still maintain my X oz per month, as I am stacking for wealth preservation, not for profit per se, so for me personally the price and form (bar, coin, or blob are all the same to me) matters less than for someone who wants to sell nice shinies (My precious) for profit.
Perhaps one way of looking at this is not what an ounce costs in $$ now, but what an ounce can buy now vs what it could buy when you were younger. I'm 50(ish), in my youth I could get minimum chips and a can of drink for 50c, now the same would be closer to $8 or 16x the difference, if I was to pay in silver it would be 1/7th oz (~3.50 oz in 1976) then and 1/3rd (ish) oz now or ~2.5x increase.
In the long run your stack will preserve your wealth, sometimes it will trend up, sometimes down, but will hold its value over the long term relative to currency regardless how much an ounce costs at any given time. So keep buying is my recommendation. If you think it will drop again soon then wait else just continue with your buying plan as normal.
I wish you well no matter what you decide.
