Does anyone know if this is safe to take while pregnant? Its been two days, my stomach is hard & I'm getting uncomfortable. It's always pebble like when I do go-my nausea medication is mostly to blame. I drink tons of water & have tried so many different foods to help just not getting enough results! I have a magnesium drink its a powder mix from natural vitally that worked wonders in the past but I haven't used since being pregnant. Currently 13 wks & 3 days. Doesn't say anything on it about consulting a doctor & the ingredients listed is just magnesium & lemon flavoring. Thanks for your advice girls!!
