Hi, I am 31years old I have an 11 year old for her I didn't know I was pregnant intill I was 2 months pregnant . I started trying to get pregnant resently . My cycle is 28 days never early never late and it last 5-6 my last period was July 11 2009 I had unprotected 5 days after my period I believe I was ovulating because I felt disconford on my left lower side then it went away after sex,I been having cramps,feeling blooted , tierd , cranky ,my belly button feels like someone is pulling on it I had to take off my belly ring then I did unprotected sex on the first and second of August . On the 3 of August which is 5 days earlier than my period I got a mucus discharge with light color blood and some brown it only lasted 48 hours and went away it was never heavy no pain usually I get very bad cramps and heavy. Does that mean I had inpanatation bleeing or not ? Please I need some advice.

It could have been from implantation, but it may have been from the recent sex as well. See what happens when your period is due for this month and try a test accordingly.
