10 First-month Pregnancy Symptoms


Mood Swings

Sometimes when you're pregnant, you might find yourself laughing and giddy one moment and teary-eyed and emotional the next. Don't be alarmed.

"Mood swings can occur during pregnancy due to the dramatic shift in hormone levels," explains Sonja Regis, a certified nurse-midwife [source: Regis]. "This may be most evident in early pregnancy when there is a rapid increase in progesterone levels."

Many women experience similar mood swings prior to the start of their menstrual cycle. Either way, this is just part and parcel of being a woman, so grab some tissues as you ride the peaks and troughs of the mood-coaster.
