Many couples experience problems when trying to become pregnant. Infertility drugs and medical treatments can increase your chances of conceiving. Medications that improve ovulation, known as fertility drugs, may help some women become pregnant. Clomid (clomiphene citrate), one type of fertility drug, stimulates your ovaries, increasing the number of mature follicles and enhancing your chances of becoming pregnant. While taking Clomid, you may conceive and begin to exhibit certain symptoms of pregnancy.

Breast Tenderness

Many women notice swelling and tenderness in the breast tissue within one to two weeks of conception. High doses of Clomid may also cause breast tenderness in some women, making it difficult to differentiate the causes of this symptom. If you are pregnant, this symptom may increase and continue as your pregnancy progresses. However if the Clomid causes your breast changes, these symptoms will subside as the drug dissipates from your system.

Nausea and Vomiting

Another common symptom of pregnancy, nausea and vomiting normally begin within two to eight weeks after conception. As with breast tenderness, high doses of Clomid can also cause some nausea and vomiting. During pregnancy, this symptom can continue through the first trimester.

Implantation Bleeding

Some women notice slight bleeding or spotting when the fertilized egg implants into the lining of the uterus. You may notice this symptom about a week before your next expected period. This spotting may indicate the presence of a growing baby.

Missing Your Period

If your fertility treatment works and the Clomid does its job, you may miss your regular menstrual period. Although some women experience light periods during early pregnancy, most experience a cessation of menstrual periods. This symptom commonly indicates the presence of a growing fetus.

Fatigue

Many women complain of fatigue during pregnancy. This symptom may occur as early as a week after conception. A side effect of high doses of Clomid may also mimic this symptom, leading some women to wonder whether they are pregnant or experiencing a side effect of their fertility medication.
