Missed Period: A missed period often is one of the first signs of pregnancy.

Metallic Taste In The Mouth: You may feel a metallic taste in the mouth at this stage.

Tender Breasts:  Your breasts may be swollen, tender, and sore due to increased blood flow to breasts.

Morning Sickness:  Hormone changes in the first trimester can cause morning sickness (nausea and vomiting). Although it is called “morning sickness”, it can occur at any time of day. Morning sickness usually goes away by the second trimester.

Fatigue: Fatigue occurs due to hormonal changes.

Heightened Sense Of Smell:  A heightened sense of smell also happens in early pregnancy.

Urinary Frequency:  Urge to urinate frequently occurs due to pregnancy hormones and pressure on the bladder. Pregnant women commonly experience temporary bladder control problems in pregnancy. Baby in your womb pushes down on the bladder, urethra, and pelvic floor muscles. This pressure can lead to more frequent need to urinate, as well as leaking of urine when sneezing, coughing, or laughing.

Light Spotting:  Light spotting occurs as the fertilized egg implants in the uterus.

Cramping:  Abdominal cramps occur due to the hectic activity going on in your uterus.
