Pregnancies have a funny way of draining you even after a pretty uneventful day.
Some women report that they have a fantastic amount of energy whilst being pregnant. Others have good and bad days, which is all totally normal, but when you cannot find the energy day after day, there may be a reason for it. Some with gestational diabetes even advised that they felt lethargic at times. Always speak with your doctor about these changes, even if you feel they may be nothing alarming.
