The first symptoms of pregnancy that you may notice vary widely: your breasts increase in size, there is an increased need to urinate, you may feel sleepier, or experience nausea, vomiting and dizziness. Or your pregnancy can also go completely unnoticed during the first few weeks. You may even think you have a period (light and superficial), when what you really experience is something known as embryo implantation bleeding. Also, bear in mind that the signs and symptoms you may experience may change from pregnancy to pregnancy. We might say these early pregnancy symptoms are specific to each pregnancy and each woman. We have compiled the best content we have available regarding the "signs of pregnancy", including all the signals your body gives throughout your whole pregnancy: from the first few days to delivery.
