We are trying for a baby from last 4 months. From last week my wife has symptoms of dizziness nausea sickness ,symptoms like pregnancy. But 2 days before she found little brown color bleeding for 4-5 hrs and whole day light watery discharge. Bleeding occur on 28th day of last period and before she have regular period on 26 th day. She saying the bleeding is different from regular period. What is this overall. When should I take pregnancy test at home.
