So I am 2 months out and ran out of my calcium and iron and didn't have time to go to my Dr office to buy more because the office closes before I get off work. So I went to Walmart and bought the wrong kind. I bought calcium carbonate instead of calcium citrate and iron in ferrous sulfate form instead of ferrous fumarate. My question is will I be ok to take these for a month or did I just waste my money?
