Fatigue
Fatigue also ranks high among early symptoms
of pregnancy. During early
pregnancy, levels
of the hormone progesterone soar. In high enough doses, progesterone can put you to sleep. At the same time, lower blood sugar levels, lower blood pressure and increased blood production may team up to sap your energy.
Slight bleeding or cramping
For some women, a small amount of spotting or vaginal bleeding is one of the first symptoms of pregnancy.
