Cramps in your feet and hands in the past two days during your 14th week of pregnancy may be caused by muscle fatigue or calcium deficiency, etc. Please refer to your doctor’s advice. 1. Muscle fatigue: This symptom may occur if the daytime labor is too much and overwork causes muscle fatigue in the hands and feet. Avoiding daily exertion will help reduce the occurrence of cramps in the hands and feet. 2. Calcium deficiency: If a pregnant woman in her 14th week of pregnancy experiences frequent cramps in her hands and feet, it may be caused by calcium deficiency. During pregnancy, parathyroid secretion increases and calcitonin secretion decreases, resulting in a large amount of calcium loss. In addition, the fetus requires a large amount of calcium during growth and development, especially bone growth, and all of this calcium comes from the mother. The amount of calcium will affect the muscle excitability, a serious calcium deficiency will cause muscle contraction, the muscle has been continuously contracted state will lead to cramps. If you have cramps in your hands and feet at times during the 14th week of pregnancy, it is recommended that you go to the hospital for a relevant checkup, and have it diagnosed and treated under the guidance of your doctor to ensure the healthy development of your fetus.
