If you have been trying to conceive, the chances are that you are looking out for pregnancy signs all the time even before your period is due. There are often many signs you are expecting a baby, although pregnancy symptoms do vary from woman to woman. Read on for a list of early signs that you have conceived and are pregnant, both before you have the chance to get a positive pregnancy test, and during the rest of the first trimester. Extreme fatigue is perhaps the earliest noticeable pregnancy symptom in many women. Admittedly, it is hard to discern this as a sign that you are expecting a baby... especially if you have been busy lately! Women who feel like taking a nap in the afternoon, and who can barely get through the day, may just be pregnant! Morning sickness or pregnancy nausea (and vomiting) is another very common early pregnancy symptom. Nausea can start as early as a few days after conception for some women, but can also kick in much later. Many women notice that they have a bloated or tender abdomen early in pregnancy. This is caused by the hormone progesterone, but can also be a sign that you are about to get your period. Have you been having mood swings? Do you cry at the slightest thing, or are you angry and aggressive? Make no mistake about it these mood swings can be among the more prominent signs you are expecting! If you have been peeing much more often than usual, you might be pregnant. More frequent urination is not exclusively the domain of third-trimester women whose bladder is being compressed by their growing baby. Again, hormonal changes are responsible for this somewhat annoying pregnancy symptom. You can notice this even before your period is due.
