Headaches

Headaches can be a common problem during pregnancy and I've had my share. According to the American Pregnancy Association, the number of headaches can increase due to lack of sleep, low blood sugar, dehydration, stress, caffeine withdrawal, hormone surges and increased blood volume. The doctor described my headaches as a vascular type because I could feel them pulsing in my head with each heartbeat. That should be no surprise when you consider that blood volume can increase by 70% to 80% during a pregnancy with twins. Probably even more with triplets.
