I have had a small amount of brown discharge in my underwear for the last two days in a row and a few times since my last period. I used tampons for the first time during my last period. I am also on the pill and this is my 6th month. I have unprotected sex and am currently being monitored by my gyno due to irregular pap tests. I am 25 years old. I am also having alot of cramping in my lower abdomin. Any clue as to what can be happening with me? Could I be pregnant? Or is it something else? Any feedback is appreciated. Thanks!
