* Missing a Period - This is one of the classic symptoms of being pregnant - missing a monthly period. If your monthly period is not regular, you may not notice it as soon as other women who get their period regularly. Many home pregnancy tests facilitate to women who have a regular period, though, and it can in some cases be a little misleading if you do not.

* Fatigue - Almost all women feel extreme tired during their first trimester, although no one is quite sure as to why this is. It is commonly thought, though, that the increase of hormones in the body is the main cause. B12 vitamins and natural, safe energy supplements would help perk you up, but check with a doctor first to see if you are pregnant, in case the supplement you hope to take would hurt your baby.

* Gagging Because of Odors - Often, pregnant women will feel a high sensitivity to certain smells - for example, the smell of a cup of coffee in the morning might make you feel so sick you can't stand to be in the same room as it. Even foods you used to enjoy may become repulsive and utterly disgusting to you.

* Got to Go Right Now - Having to urinate often is a very common symptom of being pregnant. Even before your uterus expands to accommodate a child, the amount of fluid rises in your body, causing you to feel the need to urinate more often. It is one of those symptoms that does not go away with most women until you have actually given birth, the reason for this is because the uterus expands and it presses against the bladder.

A home pregnancy test will almost always tell you for sure. But refrain from using one until a week after your missed period, though, because no matter what the box might say, it is likely not to give you a definitive answer if you use a pregnancy test too early.

If you do get a positive result, or believe you are pregnant, call your doctor and make an appointment to discuss what your options are, and what is best for you and the baby.
