I had missing periods but from last 3 months I am ok following food diet advised by doctor and decreased weight too as advised by them 4 kgs. This month I didn't get period on time and on suspect of pregnancy tested in home on 4th day of missing period with 20mlU kit. In track line I saw 2 dots size faint pink line. Whether this can be considered as + or -. Kindly advise. But I am urinating more times, got white discharge 2 days and brown one day also belly too increased a bit which can be recognized as difference and back pain too. Kindly advise please.
