10 Signs of Early Pregnancy

Tender Breasts

• Due to an increase in hormones, your breasts may feel tender, heavy, swollen or tingly as soon as two weeks after conception. They should feel less sore after the first trimester has ended because your body will have adjusted to the hormonal changes.

Slight Bleeding

• At about the time you expect your period to occur, you may experience some very light implantation bleeding. According to BabyCenter.com, it may be due to the fertilized egg burrowing into the lining of your uterus. It should only last for a day or two, and it should not be painful.

Fatigue

• A rapid increase in levels of the hormone progesterone may cause you to feel fatigued or even exhausted. Lower blood pressure along with lower blood sugar levels in early pregnancy may also be a culprit of fatigue.

Nausea

• Nausea, often referred to as "morning sickness," can occur at any time of the day in early pregnancy. It can begin as soon as two weeks after conception, but it may not occur for about a month. The Mayo Clinic says that the nausea may be due to the fact that high estrogen levels cause the stomach to empty at a slower pace than usual.

Food Aversions and Cravings

• Due to the influx of pregnancy hormones, some pregnant women find themselves craving foods that they normally would not eat. They may also feel sick at the thought of eating foods that they normally might eat or even feel repulsed at the smell of them.

Headaches

• Hormonal changes and an increase in blood flow causes more blood to reach the head than normal. This may trigger frequent mild to moderate headaches in early pregnancy.

Mood Swings

• If you have started to cry at car commercials or you feel strangely emotional about some forgotten leftovers, you may be experiencing mood swings. Mood swings are hormone-related and particularly common in the first trimester.

Frequent Urination

• As the amount of fluids in your body increase, you may find yourself needing to visit the bathroom more often than normal. Frequent urination could happen as soon as six weeks into the pregnancy and may become more frequent as the growing baby starts to weigh down on your bladder.

Raised Basal Body Temperature

• You can gauge your basal body temperature by taking your oral temperature as soon as you wake up each morning. Your basal body temperature is slightly increased right after you ovulate and stays at that point until you have your next period. However, a raised basal body temperature that lasts more than two weeks may indicate pregnancy.

Constipation

• As progesterone causes food to move more slowly through your intestines, you may experience constipation. Constipation may get worse as pregnancy progresses since the expanding uterus will end up placing more pressure on your intestines.
