How much blood is implantation bleeding? i have a small noticeable amount of brown discharge/spotting. negative preg test 2 days back. little abdominal discomfort/pain and little lower back pain. both tolerable.

Can retest in 1 week: Wait. A positive pregnancy test can tell a woman that PRIOR spotting was actually implantation spotting. 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 about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period.
