Got my period from the 7-14 march, 21st night i had little blood coming out ,today i see very little brown stains am i pregnant and when did i conciv?

Hard to guess: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. Pregnancy tests are inexpensive and sold in stores everywhere.
