The symptoms of early pregnancy - in first three months are:1. Missing a period2. Nausea and vomiting3. Frequency of urination4. Breast Changes -* Engorgement and tenderness* Brownish discoloration of nipples and areola. This happens in first pregnancy and is permanent change.* Increasing the size of areola* Clear secretions from nipple on squeezingHowever, pregnancy is never diagnosed on any of these symptoms. For confirmation of pregnancy, clinical examination is necessary. To support the clinical diagnosis, urine pregnancy test and/or ultrasonography after 8-10 days of missed period is performed. Beta Chat Doctor test is highly specific and sensitive which can give reliable results within 2-3 days of missed period. I hope you have got the answer for your query. </s>
