Contractions at 16 weeks

Sandra • Married💍Proud mother of 3 sons and patiently awaiting the arrival of baby #4 (In Shaa Allah it's a girl😍👶🏾🍼🎀)
Yesterday I was awaken with a tightening pain in across my lower abdomen. I drank water to see if it would pass, but the pain still came and went. I called the nurse on call, and was told to come in. After an ultrasound, the baby's heartbeat was great, it's growing at the proper speed (Actually measuring a week ahead of schedule😁😊), and the baby danced around the whole time lol. After 3 hours of observation, Baby S and I were allowed to go home, and told to get plenty of rest and to drink plenty of water.
