Most people find out that they are pregnant if they are sexually active and miss their period. Symptoms of early pregnancy include nausea/vomiting, breast tenderness, and fatigue (feeling tired). The only way to know for certain if you are pregnant is with an ultrasound or pregnancy test (a urine or blood test). You can do a urine pregnancy test from the first day you missed your period and after. Before this time, the level of hormones made by the pregnancy might be too low to show up on the test.
If your period is regular (it comes around the same time every month), you can use the date of your last period to figure out how far along the pregnancy is. Count from the first day of your last menstrual period, include that day and start counting up until today. If you have an irregular period or have been on birth control recently, this might not be accurate. In this case, we suggest seeking care at a healthcare facility.
