Please call your dr: Uterine contractions and blood pressure drop make me concerned that you are not drinking enough water. Make sure to drink at least 2 liters of water a day and eat regular snacks to keep blood sugar up. When you get out of bed, sit for a few minutes and then stand slowly without starting to walk to let your body adjust. If this is happening regularly it is very important to call your ob
