I am trying to become a mom and very irregular..I could go 3 months and sometimes 4 without it...but on the 21st of this monthe I started spotting light brown discharg which lasted about 1 week...and abdominal disconfort and some mild back pain..but nothing to make me cry...I took a pregnancy test after the 4th day of spotting and it is negative but I just want to know is it too early or is that a potential sign? and is it a period cause it was just mostly when I wipe myself (sorry about that) Inotice it on the tissue no red blood ...what do I do an what could it be..
