Identifying the first signs of being pregnant can be challenging because symptoms of PMS and early pregnancy are similar. Therefore it is important to listen to your body when you feel something isn't quite right. Several indicators of pregnancy like moodiness, breast tenderness and cramps are similar to a symptoms of menstruation. For the most part, early pregnancy will resemble PMS, but there are ways to help decipher the two conditions and know when to take a pregnancy test.
PMS is a cluster of symptoms that occur one to two weeks before a woman's monthly period. A majority of these symptoms parallel with the early signs of pregnancy.
Aches and pains related to PMS and early signs of pregnancy include headaches, backaches and stomach cramps. Other shared symptoms include irritability, mood swings and fatigue.
A typical first sign of pregnancy is tiredness. In early pregnancy, the fatigue is unfamiliar and uncontrollable. Rest requirements are much more intense than with the fatigue associated with PMS.
Breasts are tender a week before menstruation. In early pregnancy, the pain is far more intense, and reports of throbbing and an inability to get comfortable are common.
PMS is rarely said to cause nausea. Morning sickness due to pregnancy occurs two to eight weeks after conception and can happen before a missed period.
Menstrual cycles can often fluctuate, but a missed period paired with extremely tender breasts, fatigue and nausea are signs of early pregnancy.
