These changes are to enable the breasts to produce milk eventually.

Some people notice that they are more tired than usual.
Headaches, palpitations and dizziness are all more common during pregnancy, as is sweating and feeling hot. These signs and symptoms do not prove, but suggest that you are pregnant. The simplest way to confirm that you are pregnant is to perform a urine test which detects the presence of HCG, a hormone found in your blood and urine when you are pregnant. Home pregnancy test are available in any pharmacy, or your doctor can perform this test for you. Positive results are detectable as early as 4 days before the first missed period.
