Menstrual irregularities (including missed or late periods) can occur for a number of different reasons. Pregnancy is just one possibility. Irregular periods can be caused by hormonal imbalances, perimenopause, illness or infection, use of certain medications, and other more serious conditions. Women who are dieting or exercising excessively may also skip periods. In addition, increased stress levels and changes in routine may affect the regularity of menstrual cycles.
Since you are experiencing nausea, I would repeat the pregnancy test in two weeks. Be sure to use first morning urine and do not drink anything prior to your test. If it is still negative and you miss a second period, you should probably be evaluated by a medical professional to determine the cause.
In the meantime, watch out for the following early pregnancy symptoms, keeping in mind that each pregnancy is different and each woman may experience different symptoms or no symptoms at all. Early pregnancy symptoms include the following: implantation bleeding (many women do not experience this but when it occurs, it consists of spotting and cramping anywhere from 6 to 12 days after conception); delayed or missed period (if bleeding occurs, it is usually lighter than a regular period); swollen and tender breasts (1-2 weeks after conception); fatigue (as early as one week after conception); backaches; headaches; frequent urination (6-8 weeks after conception); and nausea or morning sickness. Usually, pregnant women first experience nausea anywhere from 2-8 weeks after conception, while others never get nauseous.
Good luck!
