Has anybody heard anything bad about consuming agave nectar ? I was drinking a lemonade that had it. I drunk about 2 or 3 good sips and then decided to look it up. It says that it's not safe during pregnancy and that it could cause contractions. I'm now cramping a little bit ! 😩😩 anybody use this sweetener ?
