I am a 21 yr old me and my fiancé have been trying to become pregnant for the past month... a week after my last period (June 26-29) on July 5 I started spotting brownish. But that only lasted for about an hour.. well yesterday July 28 I started spotting bright red. My period is due but I have not gotten it. Could this be a sign of pregnancy.. some one please help this is my 1st time I experience something like this
